Abstract: In one implementation, an amplifier comprises a load circuit comprising a plurality of inductor cells, and a drive circuit configured to receive an input signal, and to drive the load circuit based on the input signal to generate an amplified signal. The amplifier also comprises a controller configured to tune a peaking gain of the amplifier by adjusting a number of the inductor cells that are enabled.

Abstract: A first transistor (Trl ,Tr5) and a second transistor (Tr2,Tr4) cascade-connected, a wiring (lnl,ln2) which connects a drain of the first transistor and a gate of the second transistor, a capacitor (C1) whose one terminal is connected between the first transistor and the second transistor cascade-connected and whose other terminal is grounded, and a control circuit (2, 2a, 30, 40) are included in a variable inductor circuit. A control circuit adjusts the inductance value of said variable inductor by controlling a capacitance value of the capacitor or gate voltage of the first transistor or the second transistor.

Abstract: A voltage-controlled oscillator has a tuned circuit for controlling the oscillation frequency. The tuned circuit has a variable-capacitance element whose capacitance varies in response to a control voltage and a negative capacitance circuit whose impedance frequency characteristics have opposite characteristics to those of a normal capacitance, and which is connected to the variable-capacitance element. The configuration enables increasing the variation ratio corresponding to the control voltage of the combined capacitance composed of the variable-capacitance element and negative capacitance circuit, thereby broadening the oscillation frequency band.
