摘要： An on-chip receiver sensitivity test mechanism for use in an integrated RF transmitter wherein the transmitter and the receiver share the same oscillator. The mechanism obviates the need to use expensive RF signal generator test equipment with built-in modulation capability and instead permits the use of very low cost external RF test equipment. The invention utilizes circuitry already existing in the transceiver, namely the modulation circuitry and local oscillators to perform sensitivity testing. Tile on-chip LO is used to generate the modulated test signal that otherwise would need to be provided by expensive external RF test equipment with modulation capability. The modulated LO signal is mixed with an externally generated unmodulated CW RF signal to generate a modulated signal at IF which is subsequently processed by the remainder of the receiver chain. The recovered data bits are compared using an on-chip BER meter or counter and a BER reading is generated. The BER reading is used either externally or by an on-chip processor or controller to establish a pass/fail indication for the chip.

摘要： A direct current to direct current (DCDC) voltage converter is described comprising a controller and at least one converter circuit. The converter circuit comprises at least first and second inductors, each having an input and an output; a first input switch connected to the input of the first inductor; a second input switch connected to the input of the second inductor; and an output switch connected to the outputs of the inductors for selectively combining the outputs to form a parallel combination of the inductors or a series combination of the inductors. The controller generates signals for selectively connecting the first and second input switches and the output circuit between a pair of power supply input terminals and a pair of power supply output terminals. In response to appropriate signals from the controller, the converter circuit can be operated as a buck converter or a boost converter.
