Abstract
Integrated circuits with amplification circuitry are provided. The amplification circuitry may have an input terminal, an output terminal, a positive power supply terminal, and a ground terminal. The amplification circuitry may include first, second, and third stages. The first stage may provide biasing for the second stage. The second stage may provide biasing for the third stage. The second stage may provide paths for conveying an input signal from the input terminal to the third stage. The second stage may bias the amplifier to have low quiescent current and low shoot-through current. The second stage may prevent PVT variations such as supply voltage variations from affecting the quiescent current and shoot-through current of the amplifier. To increase the high-frequency response of the amplifier, capacitors may be added to the paths for conveying the input signal from the input terminal to the third stage.
