A 10bit 1MHZ SAR ADC for Automobile Electronics MCU with Rail-to-Rail Input Swing

Abstract:

Based on the DAC structure of single sampling capacitor that insures the rail-to-rail input swing a 10bit 1MHZ SAR ADC is implemented in GSMC 0.18μm 1P6M CMOS Mixed-Signal process for automobile electronics MCU. The measurement results show that in 1.8V power supply, 51KHZ input frequency and 1MHZ clock frequency, the SFDR is 71.364 dB, ENOB is 9.49 bit, total power is 2.24mW, which meet the application requirements of automobile electronics MCU.
