Abstract
A sigma delta analog-to-digital converter (ADC) circuit comprises a capacitive gain amplifier circuit having a first input to receive an input voltage and a second input; a loop filter circuit connected to an output of the capacitive gain amplifier circuit; a sub-ADC circuit including an output and an input connected to an output of the loop filter circuit; and a digital-to-analog (DAC) circuit including a DAC input connected to the output of the sub-ADC circuit, and a DAC output connected to the second input of the capacitive gain amplifier.
