Abstract
A direct current (DC) to DC (DC-DC) converter includes a comparator configured to set a pulse width of a signal pulse, the pulse width corresponding to a voltage level of an output voltage of the DC-DC converter; a digital delay line (DDL) operatively coupled to the comparator, the DDL configured increase the pulse width of the signal pulse by linearly introducing delays to the signal pulse; a multiplexer operatively coupled to the DDL, the multiplexer configured to selectively output a delayed version of the signal pulse; and a logic control circuit operatively coupled to the multiplexer and the DDL, the logic control circuit configured to adaptively adjust a precision of the DC-DC converter in accordance with a duty cycle of the DC-DC converter and a setpoint of the DC-DC converter.
