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.   Abstract: This paper presents a fully synthesized 0.4-V analog biquad filter in a 0.13-μm CMOS […]

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 TVD designs.     Abstract: Reverse engineering reveals the physical structure as well as the […]

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 presents a new multi-loop delta-sigma modulator (DSM) structure that combines the advantages of both the […]

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 spread spectrum chopping.   Abstract: This work presents a new voltage-controlled-oscillator (VCO)-based sensor readout chip […]

Researchers at UF AMSLab recently produced a Physically Unclonable Function (PUF) with less than 1.2% native instability by leveraging the resistance variation of metal vias. The target performance was achieved without the use of stabilization techniques.
