Abstract
Transition smoothing apparatus for reducing spurious input to a system under feedback control connected to a control loop. The apparatus includes a loop filter to integrate an error between an input signal applied to the loop filter and an output signal of the system under feedback control, an analog-to-digital converter to provide digitized integrated error values, a controller to generate output values supplied to the system under feedback control in response to the digitized integrated error values and in a start-up sequence to control a feedback digital-to-analog converter according to the digitized integrated error values to supply a first control signal to the loop filter and control the system under feedback control to generate a second control signal, and an alignment detector to detect phase alignment between the first control signal and the second control signal to control a smooth transition into closed loop operation of the control loop.
