CONTROLLABLE SUPPLY OF SUPPORTING VOLTAGE Russian patent published in 2007 - IPC G05F1/56 G05F1/10 G05F3/22 

FIELD: electric and radio engineering, possible use as low power support voltage sources in various functional units of analog interfaces.

SUBSTANCE: controllable supply of supporting voltage (dwg. 3) contains output transistor (1), emitter of which is connected to first output unit (2) of controllable supply of supporting voltage and to current-stabilizing dipole (3), connected to bus of power supply (4), and collector is connected to second (5) output unit of controllable source of supporting voltage, auxiliary voltage repeater (6), output of which is connected to first contact of auxiliary resistor (7). Base of output transistor (1) is connected to second contact of auxiliary resistor (7) and to additional controlling source of supporting current (8), and input of auxiliary voltage repeater (6) is connected to collector of output transistor (1).

EFFECT: creation of controlled analog of stabilitron - dipole with electronically changeable level of stabilization voltage.
