Systems, methods, and circuits for providing thermal compensation in amplifiers |
摘要 |
A communication system (300) includes amplifiers (325) having an improved thermal response. The amplifiers (325) include a Bode circuit (208) for attenuating the signals and a thermal compensation circuit (320) for adjusting the gain in response to changes in temperature. The thermal compensation unit (320) provides a non-linear impedance to offset for the non-linear performance of the amplifiers gain versus control current. The thermal compensation unit (320) has circuit paths that are selectively turned on to provide the non-linear relationship of impedance versus input control voltage.
