Claims

The comparator contains a one-shot transistors 1 and 2 connected according to the equivalent of a two-base diode, H on a resistor 3 and a capacitor 4, connected between the emitters of transistors 1 and 2 through a diode 5. A doped-down transistor 6 connected to the power supply source, the base to the transpeater the point a of the diode 5 and YOUR densatra 4, and the collector SByzanny through diode J with the output of a single vibrator, whose inputs through the puyvoy circuit; 8 are connected to the inputs, E and U of the comparator, the output bus 11 connected to the collector of the transistor 6, connected according to the scheme with a common emirter. The comparator works as follows. In the initial state of the resisters and input and active mode, the transistor is closed, the IC-capacitor 4 is bright before the voltage is approximately equal to the thermal supply source, there is no 1 pulse and no pulse during the single-shot and / or the diode S is locked. As only the difference between the compared voltages supplied through input 9 and lOi becomes positive, the ecighters of transistors 1 and 2 are locked. , at the same time, the transistor 6 is charged. At the end of the discharge of the capacitor 4, the transistors 1 and 2 are regeneratively connected and the capacitor 4 is charged by the emitter-base transition of the tracer of the source 6 from the power sources of negative displacements. At 9toM, the diode 5 is closed, and 6 is de-energized, as a result of which the collector transistor 6 proves the formation of a potential higher. 6 14 As soon as the voltage on the capacitor 4 reaches the value at which the emitter-base ftepiexw of the razistor 2 is hidden, both transistors 1 and 2 go into active mode and with a positive difference from the compared aprons, the described process repeats. Thus, the comparator is capable of producing two signals when triggered - potential and pulsed. Claims of the Invention A comparator containing a single vibrator on a SKBifeaneHTe two-base diode with an IC-circuit and a start-up circuit, an add-on transistor, an i-diode, which is supplied with. By, then, “: the goal of expanding functionality is possible-. In this case, the base of the additional transistor is connected to the averaging point of the oynovibrator.
