摘要： An oscillator circuit is formed of a differential LC resonant circuit formed of an L load differential circuit including inductance-variable portions and a capacitive element, and a positive feedback circuit formed of N-channel MOS transistors. The inductance-variable portion is configured to vary the inductance by selecting a plurality of switch circuits arranged between a plurality of arbitrary positions on a spiral interconnection layer and the input/output terminal, and thereby can control an oscillation frequency. The inductance-variable portions form an inductor pair when the switch circuit among the switch circuits coupled between the first input/output terminals is turned on together with the switch circuit.

摘要： A frequency mixer includes a first N channel MOS transistor, second and third N channel MOS transistors constituting a local oscillator signal differential pair, and having substantially identical properties, a first load, and a second load. The first N channel MOS transistor receives an RF signal at its gate. A local oscillator signal is applied to the gates of the second and third N channel MOS transistors. The drain current of the second and third N channel MOS transistors is output to the drain of the first N channel MOS transistor. An amplitude-current conversion circuit receives the RF signal and provides an output current to the drain of the first N channel MOS transistor to decrease monotonously the output current with respect to the amplitude of the RF signal.
