Abstract
© 2015 IEEE. In this paper, we present a low power hybrid spin-CMOS 5-bit Flash Analog Data Converter (ADC). Our design is based on domain wall motion based spin switches with switching current and delay of ∼50μA and 1ns, respectively, with low impedance input that enables low power operation. Spin switches can be an attractive alternative to the 'power hungry' comparators generally used in CMOS-based Flash ADCs. The state of the spin switches is converted efficiently into digital output using CMOS based latches and decoder. Our proposed 5-bit spin-based Flash ADC can operate with an average and worst case energy consumption of 1.81pJ and 3.5pJ, respectively, at 500 MS/s.
