In one embodiment, the invention is an integrated circuit (IC) including an OTP memory and conditioning circuitry. The IC receives an externally-generated DC programming voltage signal that the conditioning circuitry transforms into a programming pulse signal for programming the OTP memory. The conditioning circuitry includes: (i) reset protection circuitry for holding the programming pulse signal low if the IC is powering up, (ii) an overvoltage protection circuit for substantially preventing the programming pulse voltage from exceeding predefined boundaries, and (iii) a conversion switch for controlling the programming pulse voltage. The programming pulse voltage is (i) substantially equivalent to the externally-generated DC voltage if an enable signal is on, and (ii) substantially equivalent to a reference voltage if the enable signal is off.

An automatic gain control (AGC) for a Satellite Digital Audio Radio Service (SDARS) receiver, a method of automatically controlling gain and a SDARS receiver incorporating the AGC or the method. In one embodiment, the AGC includes: (1) an AGC function selector configured to compare first and second time division multiplexed (TDM) power signals and a nonzero threshold and select an AGC function based thereon and (2) an AGC function applier associated with the AGC function selector and configured to apply the AGC function to the first and second TDM power signals to develop therefrom an AGC control signal.
