摘要: A switching amplifier with an embedded harmonic rejection filter is disclosed. In exemplary design, the includes a generator circuit and plurality of output circuits. The receives input signal carrier at frequency generates versions drive associated different delays. may be pulse width modulation (PWM) signal. generated by delaying signal, or circuits receive provide have outputs that are coupled together implement finite impulse response (FIR) based on FIR has zeros harmonics frequency.
