 Abstract

Analog to digital converters (ADCs) are critical blocks in most signal processing chains.
Especially in low bandwidth applications, there exists a need to digitize signals with high resolution and accuracy, while at the same time, expending minimum energy.
This thesis presents a dynamic zoom ADC for use in such applications. The zoom ADC employs a high-speed asynchronous SAR ADC which works in tandem with a fully differential ΔΣ ADC. Fabricated in a 0.16-μm CMOS process, the prototype occupies 0.26 mm2 and achieves 119.1 dB peak SNR, 118.1 dB peak SNDR and 120.3 dB dynamic range in a 1 kHz bandwidth, while consuming 280 μW; resulting in a Schreier FoM of 185.8 dB.
