Abstract: An amplifier circuit includes a differential input terminal, a first power supplier, an amplifier, and a current redistributor. A differential input terminal includes a first differential pair of a p-type and a second differential pair of an n-type, and receives an input voltage. A first power supplier supplies a bias current to the differential input terminal. An amplifier receives an output current of the first differential pair and an output current of the second differential pair, and applies an amplified current to an output node. A current redistributor receives the output current of the first differential pair and the output current of the second differential pair, and provides a redistribution current to the differential input terminal.

Abstract: A power and data receiver according to the present embodiment includes: a reception coil configured to receive a power data signal from a transmission coil; a power unit forming driving power from the power data signal; and a data demodulation unit configured to demodulate a data signal from the power data signal, wherein the reception coil operates adjacent to the transmission coil to the extent that a first resonant frequency and a second resonant frequency are formed between the reception coil and the transmission coil, and the reception coil operates at a frequency greater than or equal to the first resonant frequency and smaller than or equal to the second resonant frequency in relation to the transmission coil.
