Abstract
An amplifier circuit comprises a first unit circuit and a second unit circuit. The first unit circuit may include a first current mirror circuit that includes a first active inductor including a P-channel transistor, and a first input circuit configured to generate a first differential current and a second differential current based on a pair of differential input signals. The second unit circuit may include a second current mirror circuit that includes a second active inductor including a P-channel transistor, and a second input circuit configured to generate a third differential current and a fourth differential current based on the pair of differential input signals.
