Analog to digital converters
An analog to digital converter (ADC) converts an analog signal to a digital signal. The ADC includes an input channel, a sampling circuit coupled to the input channel, an integrator coupled to the sampling circuit, and a feedback circuit coupled to the integrator. The input channel receives the analog signal. The sampling circuit samples the analog signal. The integrator receives the sampled analog signal and a feedback signal and integrates a superposition of the sampled analog signal and the feedback signal. The feedback circuit generates the digital signal according to an output of the integrator and sends the feedback signal indicative of the digital signal to the integrator.
