摘要： Disclosed herein is an electronic device (10) including a switched capacitor circuit (102) generating a boosted voltage (Vboost) from a battery voltage (Vbatt) and a monolithic transmitter (103) integrated within a single integrated circuit substrate (103). The monolithic transmitter includes a bridge (104) powered between the boosted voltage and a reference voltage and is operated based upon bridge control signals (HS_AC1, LS_AC1, HS_AC2, LS_AC2) generated by a digital core (105) within the monolithic transmitter. A tank capacitor (Ctank) and a coil (112) are series connected between output nodes of the bridge. During operation, the monolithic transmitter causes generation of a time-varying magnetic field about the coil, in turn inducing eddy currents in a workpiece (1122) disposed within the time-varying magnetic field to thereby heat the workpiece.
