Patent attributes
A digital-to-time converter includes a first node, a second node configured to receive a reference signal, and a digital-to-analog signal converter configured to couple a passive impedance to the first node. The passive impedance is selected according to the digital code. The digital-to-time converter also includes a first switch configured to selectively couple the first node to a second reference signal in response to the input signal and a comparator configured to generate the output signal based on a first signal on the first node and the reference signal on the second node. The digital-to-time converter may include a second switch configured to selectively couple the first node to a third reference signal in response to a first control signal.
