    Abstract: A constant current circuit capable of operating on a low voltage. In a constant current circuit (200) for supplying a constant current to a circuit connected to a current output terminal (102) of the constant current circuit (200), a first transistor (M1) is disposed on a current path of the constant current. A second transistor (M2) is connected to the first transistor (M1) in such a manner that their gate terminals, which serve as the respective control terminals, are commonly connected. A first current/voltage converting part (14) converts the current flowing through the second transistor (M2) and through a third transistor (M3) to a voltage. A constant current source (10) generates a reference current. A second current/voltage converting part (16) converts the reference current to a voltage. A first error amplifier (12), to which the voltages of the first and second current/voltage converting parts (14,16) are inputted, adjusts the gate voltages of the first and second transistors (M1,M2). A voltage adjusting part (20) adjusts the voltage at the gate terminal of the third transistor (M3) such that the voltage (Vd2) at an end of the second transistor (M2) gets close to the predetermined reference voltage.

    Abstract: A method and an arrangement for controlling the output voltage (V2) of a DC-to-DC converter (100). The DC-to-DC converter (100) comprises converting means (101) and regulating means (102). The converting means is fed by a first DC-voltage (V1) from the regulating means. The first DC-voltage (V1) is determined by a feed back portion (VDIV) of the output voltage (V2) from the converting means and a reference voltage (VREF). The reference voltage is derived from a pulse train (PT1). The output voltage (V2) depends on both the first DC-voltage (V1) and the pulse train (PT1). The output voltage (V2) from the DC-to-DC converter is kept constant under varying load and the output voltage level can be adjusted in an easy and flexible manner by the pulse train.

    Abstract: A process for the electrical power supply of a magnetron which rapidly varies the electromagnetic power emitted and subtantially reduces its ripple. A magnetron (4) provided with coils (3) is positioned in series with a fast regulator (2), the assembly forming a load powered by a source (1). The fast regulator (2) supplies the magnetron either at constant current, or at constant absorbed or emitted power. A slow regulator (5) acts by means of the coils (3) on the magnetron (4) in order to limit the voltage present across the terminals of the fast regulator (2) and/or the energy dissipated by the latter. Application in particular for the power supply of magnetrons.

    Abstract: A low drop-out (LDO) voltage regulator with a wide bandwidth power supply rejection ratio (PSRR) is described. In one aspect, the LDO voltage regulator includes two individual voltage regulator circuit stages. A first stage voltage regulator circuit output is at an intermediate voltage (VINT) between an input supply voltage (VDD) and a final regulated output voltage (VREG). A second stage voltage regulator circuit output is at the final regulated output voltage (VREG) and is optimized for noise-sensitive analog circuits across a wide operating bandwidth. The first stage voltage regulator circuit has a zero frequency while the second stage voltage regulator circuit has a matching pole frequency to minimize the AC response from VDD to VREG across all frequencies.
