TRIGGER CIRCUIT AND RECTIFIER, PARTICULARLY FOR A SELF-POWERED MICROSYSTEM COMPRISING A PIEZOELECTRIC MICROGENERATOR

摘要

The aim of the invention is to provide a trigger circuit for detecting a sufficiently large voltage level and for providing sufficient output power. A rectifier can also be provided, providing effectively greater output power compared to conventional solutions at the same input voltage. The trigger circuit and rectifier are intended to be useable in a self-powered microsystem comprising a piezoelectric microgenerator. The invention is characterized in that two competing field effect transistors are used in the trigger circuit. A field effect transistor connected as a diode is connected in parallel to an active rectifier in the rectifier circuit.
