Abstract: The coupled switching transistors of the digital current switch are connected to a controlled current source. Load resistors of the current switch are formed as controlled resistors. The L-level produced by a reference current branch is compared with a predetermined level by means of a regulating device which includes the reference current branch and a compensator, and the controlled resistor or the controlled current source are adjusted such that the L-level is equal to the predetermined level.

Abstract: A configuration generates a clock signal from a digital signal by evaluating signal edges of the digital signal. A first device generates a pulse at a signal edge oriented in a first direction, and a second device generates a pulse at a signal edge oriented in a second direction being opposite the first direction. Each of the devices has one terminal for receiving a digital signal and one output. A voltage-controlled, triggerable oscillator device has at least two trigger inputs, one control input and one output. Each of the trigger inputs is connected to the output of a respective one of the first and second devices, and the output of the oscillator device is an output for the clock signal. An integration device has an input connected to the output of the oscillator device and has an output connected to the control input of the oscillator device.
