Patent ID: 10826434

Abstract:
A semiconductor device includes at least one RF power amplifier (RFPA) and a voltage supply adjustment network coupled with the RFPA for providing an internal supply voltage to the RFPA based on an applied input voltage. The voltage supply adjustment network includes multiple resistors, multiple Zener diodes, a voltage return connection, an internal supply voltage connection coupled with the RFPA for conveying the supply voltage to the RFPA, an input voltage connection adapted to receive the input voltage, and a configurable connection network coupled with the resistors and Zener diodes. A subset of the resistors and Zener diodes are selectively connected together between the input voltage and the voltage return connections via corresponding conductive links to provide a prescribed output voltage to the internal supply voltage connection as a function of the applied input voltage. The connection network is configured by applying an energy source to a selected conductive link(s) in the connection network.
