Abstract
An electronic circuit includes a digital-to-analog converter (DAC), and an active integrator. The DAC converts a digital output of the electronic circuit to an analog signal and feeds back the analog signal. The active integrator includes an operational amplifier having a first input terminal that receives a summed signal of an input signal and the fed back analog signal, and a second input terminal that receives a reference voltage. The DAC includes a coupling capacitor, first switches, at least one current source, second switches, and a third switch.
