Abstract

In this paper, we present a low-power 10 Bit Successive Approximation Register (SAR) Analog-to-Digital Converter (ADC) which is suitable for low power mixed signal applications especially for IoT devices. We have used Class-AB type amplifier in Reference generator of SAR ADC to reduce current consumption and to satisfy the linearity property for better performance of ADC. The proposed circuit uses a CMOS 0.18 μm process technology and supply voltage of 5 V. The ENOB is 9.623 Bit and SNDR of 58.688 dB with current consumption of 0.44 mA.
