Simple D-class H-bridge amplifier

2 Op-Amps, 4 FETs, 2 triangle wave generators. Input is a sine wave generator, output is on a 16 Ohm load resistor.
No biasing or output capacitors needed. Great perfomance on low frequencies.
If you are going to build this circuit IRL, you should use a high-speed op-amps and MOSFETs with a low input capacitance. All the tracks on PCB between triangle wave generators, op-amps and MOSFETs should be as short as possible.
