In AoE's chapter on BJT (specifically section 2.2.3B Input and Output Impedances of Emitter followers), it derives the input and output impedances to be: Z i n = ( β + 1) Z l o a d ( 2.3) Z o u t = Z s o u r … WebThe common collector junction transistor amplifier is commonly called an emitter follower. The voltage gain of an emitter follower is just a little less than one since the emitter …
WebThe diamond buffer or diamond follower is a four-transistor, two-stage, push-pull, translinear emitter follower, or less commonly source follower, in which the input transistors are folded, or placed upside-down with respect to the output transistors. Like any unity buffer, the diamond buffer does not alter the phase and magnitude of input voltage … WebMay 22, 2024 · It is also referred to as an emitter follower or voltage follower. Common Base. The input is applied to the emitter and the output is taken at the collector. The base terminal is at the common or ground point. This configuration exhibits voltage gain but the current gain is unity at best. It also maintains the phase of the input signal.
