Abstract
In a broadband low-noise amplifier circuit to be used in a multichannel reception system, a capacitance of a variable capacitor () is controlled by a resonance frequency control circuit () so that a resonance frequency of a load unit () comprising the variable capacitor () and an inductor () matches a desired RF signal frequency. Therefore, high gain and broadband can be realized at the same time without increasing power consumption, and consequently, a reception system having reduced power consumption and high sensitivity for all channels can be realized.
