Abstract:
Temperature compensation circuits and methods for adjusting one or more circuit parameters of a power amplifier (PA) to maintain approximately constant Gain versus time during pulsed operation sufficient to substantially offset self-heating of the PA. Some embodiments compensate for PA Gain “droop” due to self-heating using a Sample and Hold (S&H) circuit. The S&H circuit samples and holds an initial temperature of the PA at commencement of a pulse. Thereafter, the S&H circuit generates a continuous measurement that corresponds to the temperature of the PA during the remainder of the pulse. A Gain Control signal is generated that is a function of the difference between the initial temperature and the operating temperature of the PA as the PA self-heats for the duration of the pulse. The Gain Control signal is applied to one or more adjustable or tunable circuits within a PA to offset the Gain droop of the PA.

Claim (Index 1):
A compensation circuit configured to monitor a target circuit having one or more performance parameters affected by self-heating during operation of the target circuit, wherein the compensation circuit is configured to be coupled to and adjust circuitry controlling the one or more circuit parameters of the target circuit sufficient to substantially offset the effect of self-heating during operation of the target circuit on the one or more performance parameters, the compensation circuit including:\n (a) at least one sensor located with respect to the target circuit so as to measure the temperature of the target circuit due to self-heating and generate an output signal T representing such temperature; (b) at least one sample and hold circuit, each coupled to at least one sensor, configured to capture a temperature T(t=t 0 ) at a time to after the commencement of operation of the target circuit, and to sample a temperature T(t>t 0 ) at times after time to and during operation of the target circuit; (c) a comparison circuit, coupled to at least one sample and hold circuit, for determining a signal \u0394T=T(t>t 0 ) \u2212T(t=t 0 ); and (d) a mapping circuit, coupled to the comparison circuit, for receiving multiple values of the signal \u0394T and mapping the multiple values of the signal \u0394T to corresponding control signal values, the compensation circuit being configured to couple the control signal values to the circuitry controlling the one or more circuit parameters of the target circuit so as to substantially offset the effect of self-heating on the one or more performance parameters during operation of the target circuit.
