CMOS MILLIMETER-WAVE VARIABLE-GAIN LOW-NOISE AMPLIFIER
摘要:
A low-noise amplifier (LNA) includes a first cascode gain stage coupled to an input node for increasing an amplitude of an RF input signal. A first variable gain network is coupled to the first cascode gain stage and includes a first inductor for boosting a gain of the first cascode gain stage, a first capacitor coupled to the first inductor for blocking a direct current (DC) voltage, and a first switch coupled to the first inductor and to the first capacitor. The first switch is configured to selectively couple the first inductor to the first cascode gain stage in response to a first control signal.
