An integrated circuit including a comparator having an enable signal input and an output and timing circuitry. The timing circuitry includes a first transistor having a control terminal, a second transistor having a control terminal, a first inverter having an input coupled to the control terminal of the second transistor and having an output coupled to the enable signal input, and a second inverter having an input coupled to the output of the comparator and having an output coupled to the control terminal of the first transistor.

Asynchronous analog-to-digital converter

An example apparatus includes: controller circuitry configured to: provide switch signals to capacitive digital to analog converter (C-DAC) circuitry, the C-DAC circuitry including switches; configuring the switches into a third configuration begin an Auto Zero (AZ) phase with a third switch in a closed state; configuring the switches into a fourth configuration to repeat the transition of the third switch to the open state corresponding to a first configuration; configuring the switches into a fifth configuration to repeat the transition of a first switch and a second switch to the open state corresponding to a second configuration; configuring the switches into a sixth configuration to repeat the transition of the third switch to the closed state corresponding to a second configuration; and performing an AZ decision with the switches in the sixth configuration.
