Abstract: A programmable gain amplifier comprises a current source that generates a first current based on a first transfer function. A voltage amplifier receives an input voltage signal and generates an output voltage signal based on a gain A, wherein the gain A is based on a control current and a second transfer function. A compensation module generates the control current based on the first current and a mapping function, wherein the mapping function is based on the first transfer function and the second transfer function to reduce the effect of an independent variable on an overall transfer function that relates the first current to the gain A.

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.

Abstract: An integrated cinema amplifier a power supply stage that distributes power over a plurality of channels for rendering immersive audio content in a surround sound listening environment. The amplifier automatically detects maximum and net power availability and requirements based on audio content by decoding audio metadata and dynamically adjusts gains to each channel or sets of channels based on content and operational/environmental conditions. A power supply stage provides power to drive a plurality of channels corresponding to speaker feeds to a plurality of speakers. The amplifier has a front panel having an LED array with each LED associated with a respective channel or group of channels of the multi-channel amplifier, and a control unit configured to light the LEDs according to display patterns based on operating status or error conditions of the amplifier.
