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.

Operational transconductance amplifier circuit including active inductor

A data transmitting and receiving system includes a first device including an encoder configured to encode row data to generate precoding data and a transmitter configured to transmit the precoding data through a transmission channel and a second device including an integrator configured to perform an integral on the precoding data, an integral sampler including a plurality of samplers configured to output sampling data based on an offset value and an output value of the integrator, a decoder configured to decode outputs of some of the samplers to generate decoded data, and a phase detector configured to detect a phase difference between the precoding data and a clock based on the decoded data and an output of another one of the samplers.
