摘要： An electronic circuit for supplying a common mode voltage to a differential output of an amplifier stage (AMPSTG). The common mode voltage at the terminals (1) and (2) is approximately equal to the reference voltage (VCM). Transistors (T1-T4) are biased in their linear region whereas transistors (T5-T8) are biased in their saturation region. In order to choose the lowest possible reference voltage (VCM), the dimensioning of the transistors (T1-T4) is such that the currents through the transistors (T1-T3) have equal current densities, and the current through the transistor (T4) has a current density which is a factor N smaller than the former current densities. The factor N is determined by the ratio of the nominal value of the current through the transistor (T1) and the minimum value of the current through the transistor (T1).

摘要： The present invention relates to a bidirectional semiconductor switch (M1, M2) with extremely low control power consumption and a bootstrap circuit which allows reliable start of operation of the switch and the hosting device after unlimited duration of mains interruptions. Intelligent control options are provided by operating from a small energy storage and no extra means are required to recover from a depleted energy storage condition. The absence of audible noise and mechanical wear also enables more frequent recharging cycles and allows smaller and thus cheaper energy storage components.

摘要： An electronic circuit comprising an amplifier includes an output terminal (OUT) for supplying an output signal (Vout) to a load, the amplifier comprising an output transistor (N2, P1) having a first main terminal coupled to a supply voltage terminal (VSS, VDD) of the amplifier, a second main terminal coupled to the output terminal (OUT), and a control terminal. In order to avoid that the output transistor (N2, P1) can enter its linear state which would cause the amplifier to act unacceptably slow for some purposes, the electronic circuit further comprises a controller adapted to prevent the output transistor (N2, P1) to enter its linear state whereby the controller is arranged for reducing a control voltage (Vcntrl) between the control terminal and the first main terminal when an output voltage (Vout) between the second main terminal and the first main terminal is below a defined level.
