common emitter amplifier with a 10k Ω output resistance could not provide very much voltage gain to a 50 Ω load resistor. The following small-signal ac . common emitter amplifier is used in forward path followed by three sections of RC phase network in the reverse path with the output of the last section being returned to the input of the amplifier. The phase shift Ф is given by each RC section Ф=tanˉ1 (1/ωrc). · Questions. 1. Does the common emitter amplifier produce a considerable amplification effect and if so, are the results consistent across transistors? 2. Does the common emitter amplifier produce a phase shift at the output and if .
common emitter amplifier is used in forward path followed by three sections of RC phase network in the reverse path with the output of the last section being returned to the input of the amplifier. The phase shift Ф is given by each RC section Ф=tanˉ1 (1/ωrc). In practice R-value is adjusted such that Ф becomes 60˚. 1. ASSEMBLY AND TESTING. Wire the amplifier circuit following your design. Measure V E, V B, and V C in quiescent conditions. Drive the input with small sinusoidal signal (output should not exceed 1 V) and measure the values of the design parameters: small signal voltage gain, quiescent current, and the frequency f -3dB. Physics , Fall Lab II - Handout 3 Input: Output: AC signal v, E i E V CC AC signal R C R E v B v, C i C Figure 2: The common-emitter ampli er with emitter resistor. 3. Since i C is essentially equal to i E, the collector current i C will wiggle, resulting in a wiggle of the collector voltage due to the presence of R C. In detail, because V CC totalV C = I C R C;.
