摘要： A circuit arrangement for regulating a parameter (e.g., duty cycle) of an electrical signal, generated by a circuit component. The regulating device includes a first integrator, which is supplied with the output signal from the circuit component, and a second integrator, which is supplied with the output signal from the first integrator. The second integrator has an operational amplifier having an inverting input, a noninverting input and an output, and the output is fed back to the inverting input via a feedback path. The inverting input receives the output signal from the first integrator. The noninverting input receives a reference signal. The output of the operational amplifier is fed back to the inverting input via a series circuit including a capacitor and a resistor. The output of the second operational amplifier provides an output signal from the regulating device, which is supplied to the circuit component as a controlled variable.

摘要： An amplifier circuit for converting the current signal from an optical receiving element into a voltage signal. The amplifier circuit includes a transimpedance amplifier having a differential amplifier and a feedback resistor, a first adjustable resistor which is connected in parallel with the feedback resistor and whose resistance value is defined by a first control signal, and a series circuit connected in parallel with the feedback resistor. The series circuit includes a first capacitor and a second adjustable resistor, whose resistance value is defined by a second control signal. The two adjustable resistors are preferably formed as MOS resistors and have the same control signal applied to them. The amplifier circuit permits the provision of a high dynamic range during the operation of a transimpedance amplifier.
