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 11):
An integrated circuit including (1) an amplifier having a Gain that droops due to self-heating of the amplifier during operation, and (2) a temperature compensation circuit, the temperature compensation circuit including:\n (a) at least one sensor located with respect to the amplifier so as to measure the temperature of the amplifier 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 amplifier, and to sample a temperature T(t>t 0 ) at times after time to and during operation of the amplifier; (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 control signal values being coupled to one or more adjustable circuits on the integrated circuit to adjust one or more circuit parameters of the one or more circuits sufficient to substantially offset the effect of self-heating on the Gain of the amplifier during operation of the amplifier.
