Abstract: Some embodiments of the invention include a control circuit to control a value of output voltage based on a feedback voltage. The feedback voltage is provided by a feedback circuit based on sense voltage that is related to the output voltage. A compensation circuit modifies the feedback voltage based on the sense voltage to further assist the control circuit to control the value of output voltage. Other embodiments are described and claimed.

Abstract: A schmitt-trigger circuit includes a differential amplifier (1), formed of at least two transistors (2, 3) having their emitters coupled to at least a first current source (4). The differential amplifier (1) has a first input for receiving an input signal (Ue) and has one output coupled, via a first current mirror (5) and a feedback transistor (8), to the second input, from which output an output signal is taken. The second input of the differential amplifier (1) is coupled to a second current source (9) as well as to a diode array which comprises at least two diode elements (10, 11) and which is arranged in parallel with the first current mirror (5) and the feedback transistor (8).

Abstract: A circuit for converting tri-state signals into binary signals comprises two current sources, each of which is connected to a common input via a respective diode path and to a respective output transistor via a further respective diode path. Depending on the potential on the input, either one of the two output transistors or both output transistors carry an output direct current.
