  • Current sense demodulator
    Patent number: 4562386
    Abstract: An apparatus for use with an amplifier regulates the current through a load according to a drive signal having first and second states and comprises switchless sensing means and polarity correction means. The switchless sensing means provides a sense signal continuously representative of the magnitude of the current through the load without the use of switching circuitry. The polarity correction means is directly coupled to the sensing means and receives the sense signal and is responsive to the status of the drive signal for providing an analog signal continuously representative of both the instantaneous magnitude and polarity of the current through the load.
