Abstract
A circuit for providing AM/PM modulation is described. The circuit includes a signal generator, which provides two phase modulated (PM) signals used to form two drive signals which are later combined in a constructive/destructive fashion. The combination of the two phase modulated signals form a signal for driving a load. When the load is driven, the resulting signal is AM/PM modulated.
