CMOS Chips We Have Built

A variety of analog, digital, and RF CMOS ASICs that the students have designed and built. The chips are for molecular measurement, electronic AI computation (bioinformatics and path planning), and communication.


Mixed-Signal Analog

Embedded Microprocessor

RFIC/Wireless/Wireline

DNA-to-Digital Conversion Array (v3)

DNA molecules in / electronic bits out. Lots of analog & digital in between. 130-nm CMOS

DNA Sequencer

Electronic bits in / DNA basecalls out (e.g., ...CCGTTAAATTGG...). RISC-V + AI bioinformatics hardware acceleration in between. Linux capable. 22-nm CMOS

10-Gbps On-Chip Scope

Fast sampling of clock and random data as expected in high-speed wireline comms. 65-nm CMOS.

DNA-to-Digital Conversion Array (v2)

As above. But different timing scheme. 130-nm CMOS

DNA Sequencer (bonded)

The above, just snug to its package frame.

100-GHz Parametric Tripler

3X frequency without the need for an idler (a good thing if you want to keep the cost down). 130-nm CMOS.

DNA-to-Digital Conversion Array

As above. Different circuitry. The granddaddy of 'em all. 130-nm CMOS.

Mixed-Signal Nonlinear Path Planner

Robot brain. Same idea as below. Has data converters for sensors (ADCs) & actuators (DACs). 90-nm CMOS.

35-GHz Parametric Mixer

Upconversion using a nonlinear cap. No DC power required. Should work at much higher frequencies. 130-nm CMOS.

Nonlinear Path Planner

Micro-bot planner. Implements a nonlinear Lyapunov-based controller processor. Optimized for a trimmed down ISA (MIPS-based) to save power, but still allows algorithm to scale. Intended to operate in subthreshold. 130-nm CMOS.

25-GHz Parametric Mixer

I don't think people tried these since WWII. The operating frequency was probably too low for lumped components in this case. 130-nm CMOS.

100-GHz Parametric Doubler

Humble doubler utilizing a nonlinear capacitance. I was surprised these things didn't appear sooner, but GaAs-based multipliers have achieved great performance. This approach gives some hope for tighter integration with other system components. 130-nm CMOS.

4-GHz Active Scatterer

Wireless signals that bounce off this thing get phase modulated. It makes otherwise stationary communicators look like they are moving. This prevents wireless communicators from sitting in deep fades for too long and thus enables correction codes to do their job. Measurement results implied 4X improvement in WLAN coverage area. 130-nm CMOS.
