Abstract: As any analog-to-digital converter (ADC) with a front-end sample-and-hold (S/H) circuit, successive approximation register (SAR) ADC suffers from a fundamental signal-to-noise ratio (SNR) ...
Abstract: This paper describes an error-feedback (EF) NS-SAR ADC featuring a low-cost sampling kT/C noise cancellation (SNC) technique. It fully reuses the EF hardware with just a slight modification ...
