Abstract
A power transfer device includes a first power supply node, a second power supply node, and an oscillator circuit configured to convert an input DC signal across the first power supply node and the second power supply node into an AC signal on a differential pair of nodes comprising a first node and a second node in response to a control signal. The oscillator circuit includes a regulated power supply node and an active shunt regulator circuit configured to clamp a peak voltage level across the regulated power supply node and the second power supply node to a clamped voltage level. The clamped voltage level is linearly related to a first voltage level on the first power supply node.
