  • RF peak-to-peak detector with wide dynamic range
    Patent number: 6836187
    Abstract: A temperature and process compensated voltage controlled amplifier circuit achieves a prescribed power level over a wide dynamic range. The amplifier circuit has a power amplifier and a peak-to-peak detector that are integrated parts of an integrated circuit. The power amplifier outputs an amplified RF signal having an amplified peak-to-peak voltage amplitude. The peak-to-peak detector receives the amplified RF signal and generates a detector output signal having a direct current voltage component that is substantially proportional to the amplified peak-to-peak voltage amplitude. The power amplifier receives the detector output signal and uses it to achieve an amplified peak-to-peak voltage amplitude corresponding to a prescribed power level. The peak-to-peak detector includes transistors with identical threshold voltages.
