1. Circuits with ideal OpAmps

1.1 OpAmp for temperature measurement

The AD590 is a temperature sensor, which provides an impressed current of 1µA/K.

1.2 OpAmp as voltage reference

1.3 Limited integrator

This circuit provides limited integrator. There is UI < 0.

1.4 OpAmp circuit

Calculate UO/UI.

1.5 Amplifier circuit, high pass filter

1.6 Circuit with two OpAmps

1.7 Triangle rectangle generator

Develop a circuit which generates the above waveform. There are rail to rail Operational Amplifiers available with a supply voltage of +/-15V. Resistors may be used any desired, capacitors from the standard series E6. It is important to ensure that no OpAmp output is loaded with less than 2kΩ.

1.8 Subtracting amplifier

The inputs of the circuit are supplied with wires of different length. These are modelled by RC elements. Both lines are connected together on the other side. There, the voltage UI is applied.

1.9 Rotating field detection circuit

1.10 Current source

It is assumed that the operational amplifier will operate in negative feedback.

1.11 Subtracting amplifier
