Abstract
An integrated circuit configured to perform hybrid built in self test (BiST) of analog-to-digital converters (ADCs) is described. The integrated circuit includes an ADC. The integrated circuit also includes a BiST controller that controls the hybrid BiST. The integrated circuit further includes a ramp generator that provides a voltage ramp to the ADC. The integrated circuit also includes a first multiplexer that switches an input for the ADC between the voltage ramp and a voltage reference signal. The integrated circuit further includes feedback circuitry for the ramp generator that maintains a constant ramp slope for the ramp generator. The integrated circuit also includes an interval counter that provides a timing reference.
