Abstract
A DPWM () has a locked loop () which receives an input clock signal and provides an out-of-phase delayed clock at the output of each cell in the loop (). A multiplexer () selects one of the cell outputs at any one time. This allows the DPWM () to have a greater resolution which would otherwise be achieved with the same input clock. The resolution is further increased using an interpolator. A programmable module () has a control block () which interfaces with external CPU and DSP hosts and transmits programmed parameters to finite state machine controllers (), each providing an independent output.
