Abstract :
In this paper a stochastic approximation register ADC is proposed. The ADC is capable of achieving an ENOB of up to 10 bits. The ADC is composed of a variable noise engine, a bank of comparators with Gaussian offset noise, and a DAC. The ADC is simulated to achieve over 10 ENOB across various non-idealities using a comparator bank containing 1200 digital-cell based comparators with an input referred offset standard deviation of 12 mV.
