Audio amplifier
An audio amplifier is provided. The audio amplifier includes an amplifier, a biasing circuit, and a time-delay circuit. The amplifier circuit is for amplifying audio signals. The biasing circuit is for providing a bias voltage to the amplifier circuit to actuate the amplifier circuit. The time-delay circuit is for receiving a pulse signal and delaying the bias voltage to avoid a sudden actuation of the amplifier circuit based on the pulse signal. The time-delay circuit comprises a first input for receiving the pulse signal, a first resistor coupled to the first input, a first output coupled to the biasing circuit, a first BJT whose base, emitter, collector are respectively coupled to the first resistor, ground, and the first output.
