High frequency CMOS differential amplifiers with fully compensated linear-in-dB variable gain characteristic |
摘要 |
A high frequency CMOS differential amplifier which comprises: a variable gain amplifier which amplifies differential input; a temperature sensing circuit; a gain-slope correction circuit which produces an intermediate control voltage as a function of temperature, thereby compensating for a change in slope of the gain control characteristics with temperature of the variable gain amplifier; a gain compensation circuit which is used to correct temperature/process variations of MOS transistors in high frequency differential amplifiers; and a bias control circuit.
