Abstract:
An exemplary embodiment of an analog multiplier may include a voltage controlled resistance circuit, a first transistor and a second transistor, where the resistance of the voltage controlled resistance circuit is based upon a first input voltage. The current passing through the voltage controlled resistance circuit is based upon a second input voltage. The first transistor and the second transistor form a current mirror to mirror the current passing through the voltage controlled resistance circuit to provide a power supply control current to a wideband code division multiple access radio frequency power amplifier.
