ABSTRACT:
A power sensor circuit for use in a convergence system which comprises a convergence circuit for generating a convergence correction signal. The power sensor circuit receives at least one supply voltage and generates an output signal having a magnitude selected in accordance with whether the at least one supply voltage is above a first threshold. The output signal is coupled to the convergence circuit, which enables or disables the convergence correction signal in response to the magnitude of the output signal.
