The combined resistance of these two equals the ratio of the collector and base resistors of the sensing transistor and the emitter follower current is lower than that in the emitter replacement transistor. This provides a circuit that, in circuit integration, gives a source current independent of...
There is provided a constant-current source having first current mirror circuit, connected between a first fixed voltage terminal and first and second nodes, having a first current gain; the first mirror circuit passing a first current through the first node based upon the first fixed voltage and...
An improved circuit for controlling the maximum current in a MOS power transistor, in which resistor is in series with the drain- source path of the MOS power transistor. The supply terminal of a transconductance operational amplifier is connected to the output of a voltage-raising or charge pum...
the collector current output is less than the emitter current input resulting in a current gain for this type of circuit of “1” (unity) or less, in other words the common base configuration “attenuates” the input signal.The
Just a single transistor, a ferrite inductor, and apiezo transducer, that's all you will need to make this circuit “buzz” or rather “twit” for you, with an output that may be quite loud and ear piercing. The simple piezo buzzer circuit described here actually works in a quite unique...
prevent a power transistor from being damaged by an excess current due to the short-circuit of load, etc., by setting the clamping voltage of a snubber circuit below the potential of a DC power source, before the power transistor is turned off at time of generating the excess current. CONS...
A power transistor switched power supply connecting a power source to a capacitive load, including a circuit and method for limiting the inrush surge current through the power transistor. The control gate of a junction field effect transistor (JFET) is coupled between the conductive path of the ...
Diodes ensure current flows in only one direction, helping to stabilize the circuit. Figure 1. This diagram shows a two-input TTL NAND gate with four transistors: Q1, Q2, Q3 and Q4; four resistors: R1, R2, R3 and R4; and a diode: D. Q1 is the input transistor. Q2 functions as a...

This means that by connecting their terminals to a circuit, they will normally conduct current across drain to source, without any voltage provided to the base. To turn off these FET transistors, you apply a voltage (VGS) to the gate-source terminal, called the cutoff voltage, which stops...
