ABSTRACT:
An additional signal is supplied to an integrated circuit, including a voltage regulator and a plurality of electronic circuit elements, by impressing the signal on a terminal coupled to the voltage regulator. Circuitry in the integrated circuit recover the signal by detecting the voltage regulator response thereto. Method and apparatus with voltage regulators of shunt and series type are described.
