Abstract:
1. An electronic amplifier, comprising: a configurable integrated circuit device structured to (i) synthesize at least a first signal and a second signal, wherein the configurable integrated circuit device includes a CPU, a first numerically controlled oscillator and a second numerically controlled oscillator, wherein the first numerically controlled oscillator is structured to synthesize the first signal based on one or more first parameters generated by the CPU and wherein the second numerically controlled oscillator is structured to synthesize the second signal based one or more second parameters generated by the CPU, (ii) scale the first signal to create a scaled first signal and scale the second signal to create a scaled second signal, (iii) create a discrete time composite signal which comprises a summation of at least the scaled first signal and the scaled second signal, (iv) create a discrete time pulse width modulated signal based on the discrete time composite signal, and (v) generate a number of control signals based on the discrete time pulse width modulated signal; a power switching stage receiving the number of control signals from the configurable integrated circuit device, wherein the number of control signals are configured to control the power switching stage; and a low pass filter coupled to an output of the power switching stage.
