Abstract

A low power 10b A/D converter (ADC) for passive RFID sensor applications was designed and measured. The chip contained an offset voltage self correction sample-and-hold circuit (SHC) having a large input impedance required by capacitive sensors. The ADC is a successive approximation type converter used at clock frequency of 2 kHz. Sampling frequency was 75 Hz. Measured integral (INL) and differential (DNL) nonlinearities were 3.3 LSB and 4 LSB. The stand by power consumption was 2.3 muW at 1.8V supply voltage
