Abstract: A rectifier circuit includes a MOSFET (M1), and a first Zener diode (D1) or a first Zener-emulator (E1) that emulates the D1. The circuit conducts current in a forward direction from an input to an output, and substantially blocks current in a reverse direction. The M1 is characterized by an on-resistance. A cathode of the D1 or a cathode-contact of the E1 is connected to the input, and the anode of the D1 or an anode-contact of the E1 are connected to the source. The E1 includes a first small-Zener-diode (D11), a first resistor (R11) and a first transistor (M11) interconnected such that the E1 emulates the D1, and is characterized by a Zener-voltage. The Zener-voltage and the on-resistance are selected such that a stored-charge in the body-diode is less than a forward-charge-threshold when current flows in the forward direction, whereby the reverse recover time of the body-diode is reduced.

Abstract: A controller includes a high-side circuit, a low-side circuit, a level-shift circuit, and a data-validation circuit. The high-side circuit is referenced to an offset-voltage reference that is offset voltage-wise relative to a ground reference of the controller. The low-side circuit is operable to output a control signal for the high-side circuit. The control signal is referenced to the ground reference. The level-shift circuit is configured to output a shifted signal to the high-side circuit that is referenced to the offset-voltage reference and based on the control signal. The data-validation circuit is configured to receive the shifted signal, determine a first value of the shifted signal at a first instant, determine a second value of the shifted signal at a second instant different in time from the first instant, and validate the shifted signal based on a determination that the first value and the second value correspond.
