Patent ID: 7400191

Claim:
A switching amplifier, comprising: a modulator for converting a main input signal to a high frequency modulated switching signal and for providing voltage amplification of the main input signal; a power output stage coupled with an output of the modulator for receiving the voltage amplified main input signal and for providing a current amplification of the main input signal for providing a main output signal for driving a load; and a feedback module for correction of the main output signal in relation to the main input signal, with the modulator comprising: a constant switching current source and voltage level translator for providing constant current and voltage to the power output stage; a comparator coupled with an input of the constant switching current source and voltage level translator through a regulator mechanism, with the comparator comparing the main input signal with the main output signal for maintaining a linearly amplified replica of the main input signal; a ramp generator coupled with the input of the constant switching current source and voltage level translator through the regulator mechanism, with the ramp generator providing a modulation frequency for the switching amplifier and; the regulator mechanism coupled with the input of the constant switching current source and voltage level translator for regulating a voltage of the switching amplifier.
