The remote variable resistor functions as a voltage-controlled resistor whose resistance changes based on an applied voltage.

A 1 kΩ collector resistor and a 330 kΩ base resistor has never failed me for a small-signal self-biasing audio amplifier, I’m nothing if not a creature of habit.

A BJT transistor with an emitter degeneration resistor (R e) is shown in Figure 1.Figure 1 A BJT transistor with an emitter degeneration resistor (R e). Note the following equations for the transistor ...

The base will look like the emitter resistor times beta in ohms (2220 ohms). So the voltage divider of R1 and R2 really has 2200 ohms in parallel with R2 . To get the 12 V knocked down to 2.8 V ...

IT is well known that changes in the d.c. characteristics of transistor amplifiers with temperature are particularly severe, and tend to limit the range over which these devices can operate. The d ...

Remote Technologies Incorporated (RTI) today announced that it is now shipping its vIRsa Mouse IR emitter. ... "From its flexible film adhesive to its built-in resistor, every aspect of the vIRsa is ...

One diode from a matched pair is used for the emitter load (D2), and D3 is a reference diode employed to enable differential measurements. The diodes are 1N4148-type devices.

Calculating the appropriate resistor values for a photocoupler isn’t complicated, ... Closely reading the PS8902 datasheet indicates that emitter forward voltage V F can be as high as 1.85 V: ...
