    摘要: An embodiment of the invention relates to a controller that includes a delta-sigma modulator to produce a one-bit, oversampled signal representing a measured characteristic of a process, and a delta-sigma modulator to produce a one-bit, oversampled signal representing a set-point value for the characteristic. A multiplexer selects a partial sum based on a difference of the oversampled signals to produce a control signal for the process. The controller that produces the control signal for the process can be a PID controller.
