摘要： A circuit for generating a band gap reference voltage (VREF) includes circuitry (I3×7) for supplying a first current to a first conductor (NODE1) and a second current to a second conductor (NODE2). The first conductor is successively coupled to a plurality of diodes (Q0×16), respectively, in response to a digital signal (CTL-VBE) to cause the first current to successively flow into selected diodes. The second conductor is coupled to collectors of the diodes which are not presently coupled to the first conductor. The diodes are successively coupled to the first conductor so that the first current causes the diodes, respectively, to produce relatively large VBE voltages on the first conductor and the second current causes sets of the diodes not coupled to the first conductor to produce relatively small VBE voltages on the second conductor. The relatively large and small VBE voltages provide differential band gap charges (QCA-QCB) which are averaged to provide a stable band gap reference voltage (VREF).

摘要： An operational amplifier having an adjustable input offset is provided that can improve dynamic performance by allowing processing of the input signal in continuous-time. The amplifier circuit comprises an input source and an operational amplifier configured with an adjustable input offset circuit. The adjustable input offset circuit enables cancellation of the offset error from any input sources prior to being translated or gained up by the operational amplifier, thus improving the dynamic range of the operational amplifier. The adjustable input offset circuit can be configured within a signal path of an auto-zero loop of the operational amplifier, or with a continuous-time implementation.

摘要： A temperature curvature compensation technique and circuit can be realized through the generation of a temperature curvature compensation voltage provided by measuring the difference between the base-emitter voltage Vbe of two different transistors operating at two different temperature coefficient quiescent currents. This voltage difference measured between two such transistors results in a scaled voltage that is representative of the temperature curvature of the base-emitter voltage Vbe of a transistor, and which can then be summed to the bandgap reference output to provide a temperature compensated, bandgap reference voltage. The above method can be carried out in an amplifier circuit configured to receive and sum the temperature curvature compensation voltage and the bandgap reference output voltage into the temperature compensated, bandgap reference voltage. In addition, the summing of the temperature curvature compensation voltage and the bandgap reference output voltage may be realized through the application of a dual differential pair amplifier configuration which operates as a gm source. Further, scaling of the respective input voltages for each differential pair can be provided by the amplifier circuit. Moreover, the dual differential pair amplifier may be incorporated into a buffer amplifier configuration to receive a bandgap reference voltage and provide a buffered output or, integrated with a bandgap reference circuit directly into an amplifier circuit.

摘要： Curvature in a reference voltage produced by a switched capacitor band gap reference circuit is compensated by producing a first .DELTA.V.sub.BE voltage by causing first and second PTAT/R currents to flow through a first .DELTA.V.sub.BE -generating circuit. The first .DELTA.V.sub.BE voltage is applied to a first terminal of a first capacitor having a second terminal coupled to a summing conductor of an operational amplifier producing the reference voltage. A second .DELTA.V.sub.BE voltage is produced by causing a third PTAT/R current and a fourth current to flow through a second .DELTA.V.sub.BE -generating circuit. The second .DELTA.V.sub.BE voltage is applied to a first terminal or a second capacitor having a second terminal coupled to the summing conductor. First and second charges are transferred from the first and second capacitors through the summing conductor into a feedback capacitor coupled between the summing conductor and an output of the operational amplifier to produce the compensated reference voltage on the output of the operational amplifier. A technique of storing a voltage on the feedback capacitor equal to a V.sub.BE voltage minus a voltage on the summing conductor during a charging phase, and then connecting the feedback capacitor between the summing conductor and the output of the operational amplifier cancels the offset voltage of the amplifier.

摘要： A programmable offset amplifier includes first (M1) and second (M2) input transistors having differentially connected sources and gates coupled to first (Vin+) and second (Vin−) input voltages. A tail current (Itail1) is shared between the first and second input transistors.

An output stage (13) has a first input (+) coupled to the drain of the second input transistor and a second input (−) coupled to the drain of the first input transistor. Programmable voltage changes are produced on input elements of programmable input offset circuitry to cause changes in offset voltages associated with electrodes of the input transistors which are reflected back to the amplifier input to provide a large programmable input-referred offset voltage.
