摘要： A circuit (10, 100) is used to perform voltage regulation. In one embodiment, a voltage regulator (11) is used in conjunction with an output transistor (24) to form a circuit (10) which operates to regulate the voltage drop from a first node (30) to a second node (28). This second node (28) may be used to provide power to circuitry (27). The areas of several transistors (20–25) in circuit (10) may be adjusted so that negative and positive temperature coefficients may be balanced such that the circuit (10) behaves as desired over a range of voltages and temperatures. Note that in one embodiment, circuit (10) is a 2-terminal device.

摘要： Systems, methods and circuits for regulator minimum load control. In one particular case, a system is provided that includes a load control circuit and a switched load. The load control circuit includes a reference current, and a sense current representative of a load current. In addition, the load control circuit includes a comparator circuit that drives a control signal in response to a comparison between the reference current and the sense current. The switched load is electrically coupled to a load voltage signal to provide loading to the load voltage signal. The switched load is operable to switch between a first loading factor and a second loading factor in response to the control signal.

摘要： Systems, methods and circuits for sense circuit calibration. In one particular case, a system is provided that includes a sense circuit, a calibration circuit, and a sample and hold circuit. The sense circuit provides a sense current that is derived from either a reference current or a load current depending upon the operational state. The calibration circuit includes a calibration amplifier electrically coupled to the reference current and to the sense current. The calibration amplifier outputs a calibration signal representing a difference between the reference current and the sense current. The sample and hold circuit is operable to store a value representative of the calibration signal, and useful in forming a calibration offset current applied to the sense current.

摘要： A RSD analog to digital converter has an RSD stage that in turn has a switched capacitor integrator (SCI). The SCI uses an operational amplifier. A capacitor, which operates as a offset compensation capacitor, is precharged to the offset voltage of the operational amplifier during a precharge phase. The next phase switches this offset compensation capacitor in the path of the capacitors which are used to perform the integration. The effect is that the offset of the operational amplifier is corrected by the use of the compensation capacitor that had been precharged to the offset voltage during the previous phase.
