A fully synthesized 0.4-V analog biquad filter in a 0.13-μm CMOS technology using digital standard cells. In contrast to a custom-designed inverter-based amplifier in the conventional design, a new NAND-/NOR-gate-based micro-operational amplifier (uOP) operating in weak inversion is proposed.  … Read More

The AMS Lab has developed a family of logic devices that are resistant against optical reverse engineering. Our threshold voltage device logic family, coined E-TVD, achieves 40% less power, 45% speed improvement and 34% smaller footprint when compared to conventional… Read More

The Correlated Dual Loop Sturdy MASH (CDL-SMASH) removes the need for explicit quantization error extraction, while still retaining all of the benefits of SMASH and MASH architectures such as improved loop stability, and aggressive noise shaping.   Abstract: This article… Read More

Novel VCO-driven chopping technique enables 42dB SNR with 800uV peak to peak input signal while consuming less than 2 uW. The technique uses a VCO quantizer to generate a speudo-random chopping frequency without the need for complicated circuitry associated with… Read More
