A PIN diode behaves like an open circuit, like a short circuit, and anywhere in between. It can be current-tuned to a required impedance, such as 50 â ¦, for impedance-matching purposes. A PIN diode ...

BC557 PNP transistor or equivalent; 10uF electrolytic capacitor (timing) 2. For the Op-amp Amplifier. LM358 or comparable opamp; 10uF electrolytic capacitor (decoupling) 10nF ceramic capacitor (AC ...

The selection of the transistor is essential for this project. In the above circuit, we used BC337-25 transistors. This transistor provides pretty good gain to the input signal. One can use other ...

Block diagrams are presented of switches, memory units, arithmetic units, and other basic components. Estimates are given for the number of parts required in the units. It is concluded that a ...

The circuit, as we saw earlier in the circuit diagram, contains an electronic switching component (transistor, MOSFET or other. It can be switched on and off (at high speed) by means of a pulsating ...

Thus the three basic bipolar transistor circuit configurations have equivalents with a FET; common-emitter becomes common-source, common-base becomes common-gate, and an emitter follower becomes a ...

The paper deals with circuits containing diodes and the Ebers-Moll modeled bipolar transistors. The basic and still open question of finding multiple DC solutions is discussed. To find all the DC ...
