ABSTRACT:
A switching circuit constructed according to the invention includes an input node, an output node, a reference node, a switch, and a feedback control circuit for cycling the switch in a series of cycles of variable switch duty ratio in order to produce a chopped signal at the output node. One form of the feedback control circuit integrates the chopped signal during each cycle in order to produce a feedback signal indicative of the average value of the chopped signal during each cycle. A comparator circuit produces a control signal indicative of an occurrence of a condition in which the level of the feedback signal equals the level of the reference signal, and a switch control circuit varies the switch duty ratio according to the occurrence of that condition in order to maintain the average value of the chopped signal linearly related to the reference signal. Another form of the feedback control circuit produces a feedback signal indicative of the difference between the time-integrated value of the chopped signal and the time-integrated value of a reference signal coupled to the reference node during each cycle. A comparator circuit produces a control signal indicative of an occurrence of a condition in which the difference between the time-integrated value of the chopped signal and the time-integrated value of the reference signal is zero, and a switch control circuit varies the switch duty ratio according to the occurrence of that condition without integrator reset.
