Abstract: A compensation circuit adapted to receive an input signal for a circuit element to be compensated. The input signal is used as an address to a memory at which a compensated signal is stored. The stored compensated signal is output to the circuit element as the compensated signal therefor. In a specific implementation, the command input is received by a shift register. The shift register converts a serial input to a parallel output. The parallel output of the shift register is combined with the output of a temperature sensor to provide an address for the memory. The command input data includes an address to the particular circuit element to be compensated. The temperature data is used to select a particular page of memory and the remainder of the command input data is used to select data from that page for output as the compensated signal for the selected element. In the illustrative embodiment, the components compensated are automatic gain control amplifiers.
