ADC SNR effects due to parasitics, mismatch, and noise

Successive-approximation-register (SAR) analog-to-digital converters (ADCs) are commonly used in applications which require medium to high resolution. The major benefits of SAR ADCs are high ...

Studying DAC capacitor-array degradation in charge-redistribution SAR ADCs

Abstract: In this paper, system-level behavioural models are used to simulate the aging-related degradation effects in the DAC capacitor array of a charge-redistribution successive approximation ...

500-MS/s 5-bit ADC in 65-nm CMOS With Split Capacitor Array DAC

Abstract: A 500-MS/s 5-bit ADC for UWB applications has been fabricated in a 65-nm CMOS technology using no analog-specific processing options. The time-interleaved successive approximation register ...

A self-calibrating low-power 16-bit 460 kS/s SAR ADC for microcontroller applications

Low cost microcontrollers are increasingly expected to provide high performance analog functions for applications that previously used stand-alone ADCs. These applications include power metering, ...

Build Your Own Capacitor-Free High Pass Filter

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it ...
