摘要： A transimpedance amplifier includes a first and a second power supply terminal for receiving a positive constant supply voltage, wherein the second power supply terminal represents a ground, and an input terminal adapted to be connected to a current source. The transimpedance amplifier further comprises a transistor comprising a control terminal and two further terminals, wherein the input terminal is connected to the control terminal of the first transistor. An inductor is connected between the first of the two further terminals of the transistor and the first power supply terminal, and a bias network is connected between the second of the two further terminals of the transistor and ground. Specifically, the transimpedance amplifier is configured such that the resistance between said first of said two further terminals of said first transistor and said first power supply terminal is small enough, such that said transimpedance amplifier operates as a differentiator.

摘要： A regulated power supply circuit includes a voltage reference circuit arranged to generate a reference voltage and an output device responsive to a control signal to supply a load from a voltage source. A control circuit is arranged to compare an output voltage at the load with the reference voltage. The control circuit includes a comparator comprising a long-tailed transistor pair having a first input to which the reference voltage is applied, a second input to which the output voltage is applied, and an output connected to an input terminal of the output device. The control circuit applies a correction signal to the output device via a single semiconductor junction to regulate the output voltage, thereby minimising propagation delay in the control circuit. The circuit may include a primary voltage regulator arranged to supply the control circuit at a lower voltage than that of the voltage source.

摘要： An operational amplifier input circuit for preventing phase reversal and maintaining performance for inputs outside the common mode range includes a pair of differentially connected transistors for receiving respective differential inputs, and a folded cascode pair of transistors that are coupled to the differential transistors. A pair of resistors are connected between a reference potential and the current circuits of the differential and cascode transistors to produce resistor voltages that control the respective cascode transistors' currents. The differential transistors respond to an input by producing a forward biased parasitic diode in one of the differential transistors. A phase compensation circuit responds to the input by shifting the resistor voltage for the other differential transistor to prevent a phase reversal of the resistor voltages. A current compensation circuit responds to the input by shifting the cascode transistors' base-emitter voltages to decrease their bias currents, and thereby limit their currents to a range within which the operational amplifier does not latch up.
