Who We Are
The eoSemi team consists of four experienced and highly qualified (2 PhD) IC designers with a very strong business focus. This team has significant outreach to both engineering and business-minded colleagues offering additional skill sets and “bandwidth”, and is supported by respected industry mentors.
A wealth of business and engineering knowledge has been gained from past experiences with large IDMs and startup ventures such as Philips, Motorola, Pilkington Microelectronics, STC, Chartered Semiconductor, Anadigm as well as academic teaching experience at UMIST and Lancaster Universities.
The team has over 70 years’ professional experience, including 5 years’ business management, 35 years’ analog/mixed signal engineering experience, 15 years’ custom/semi-custom digital design experience and software and systems design.
Separate patents held by team members: 14

topIan Macbeth has 20 years’ experience in the semiconductor industry specialising in analog CMOS IC design including research, IP development, product development, management and enterprise creation with Philips Research, Pilkington Microelectronics (PMeL), Motorola and Anadigm. He combines an innovative technical background with a good track record of evolving enterprising ideas into business opportunity.
He was Chief Technical Officer, VP Engineering and founder (in January 2000) of Anadigm, a VC-backed leading supplier of field programmable analog array (FPAA) IC and software systems. Over $35M raised through 3 rounds of VC funding. Ian was company director & management team member and established Anadigm's 1st class international product development teams and engineering processes. Drove business vision and HW/SW development for 3 generations of FPAA systems, all of which were delivered on time & budget. Developed close working relationships with customers seeking programmable signal processing solutions for RFID, audio, and industrial & medical control systems.
A 1985 BSc Hons graduate of the University of Edinburgh, Ian is author of 15 technical publications - two winning institutional awards. He holds 8 patents on analog IC and system design including the architectural basis for Anadigm's programmable analog IC products.
topDr Adrian Bratt has over 13 years’ experience in industry, following an academic research focus. He has broad experience in CMOS analogue IC design at Pilkington Microelectronics (PMeL), Motorola and Anadigm with approximately 20 parts reaching production from the Motorola HCS12 microcontroller family and the Helix, Vortex and APEX product families at Anadigm.
Adrian led a team of 9 IC design engineers at Anadigm, working closely with the software and firmware teams, responsible for the full product cycle from detailed engineering specification to production, test and field support. A strong engineering team leader, Adrian draws on a rich experience of various CMOS mixed-signal block design including ADC, DAC, analogue continuous time and sampled data filters, ESD circuits, PLL, POR, bandgap reference and comparator circuits and others.
Adrian holds a BSC in Physics & Geology from Manchester University, an MSEE (Hons) in IC Design from UMIST and a PhD in Analogue IC Design from Manchester University. He is a visiting lecturer at Lancaster University. He is author of 16 publications and 2 patents.

Dr Steve Harrold has over 23 years experience in electronics. He has extensive industrial and commercial experience gained in periods of employment at STC and Anadigm, as well as academic and project management experience gained at UMIST. He is an experienced designer of both digital and analogue systems, in technologies ranging from silicon bipolar and CMOS to GaAs, and frequencies from DC to multi-gigahertz.
Recent experience had focused on the design and implementation of general-purpose op-amps offering high-gain, fast-settling and low-noise for commercial field programmable analogue arrays (FPAAs),system-level mixed-signal floor planning & parasitic analysis, near field RF interface design, and DSP analysis.
Steve holds a BSc in Applied Physics and Electronics from Durham University, a PhD in Engineering Science from Exeter University, was Senior Lecturer in Electronic Engineering at UMIST, and has written 4 patent applications and 46 technical publications.
topJon has over 15 years’ experience in digital and system-level mixed-signal design at Pilkington Micro-electronics, Motorola and Anadigm.
A custom and semi-custom digital systems specialist, at Anadigm Jon was responsible for architectural design and implementation of user interface and all digital CMOS IC subsystems for the entire Anadigm FPAA family using both full custom VLSI design flows and Verilog based synthesis techniques. Additionally, he has been responsible for the design of SRAM memory, CRC16, digital PLL components, FPGA architecture and integration, SPI and other proprietary interface designs, a 1GHz timing detector as well as having responsibility for several semi-custom ASICs.
His close involvement with Anadigm’s customers drew on his skills for analogue, digital and mixed-signal systems-level problem solving across a wide range of industrial applications and design tools.
Jon holds a BSc (Hons) in Electrical Engineering from Salford University and holds two recently-granted patents.
