Npn voltage follower
Web1 dag geleden · The output voltage tracks the voltage on capacitor C1 because U2 is configured as a voltage follower. C1 is charged to this voltage by the output current of U1 through the D2. R1 prevents the U1 from exceeding its short circuit output current and isolates U1 from the capacitance of C1 which prevents ringing or even oscillations. WebThe breadboard connections are shown in figure 1. The output of the channel A voltage generator, CA- V, is connected to the base terminal of Q 1. The collector terminal is connected to the positive (+5 V) supply. The emitter terminal is connected to both the 2.2 KΩ load resistor and the channel B scope input CB-H.
