Jfet unity gain buffer

WebCombined with a volume attenuator and input switches, it is a unity gain active pre-amplfier. With an additional voltage gain stage powered by the Z-reg outputs, it becomes a full-fledged pre-amplifier. It's a recording loop buffer. Tape outputs seem a bit archaic these days, but the B-boards can be used in this capacity. rjm003.geo at yahoo.com WebThe gain of the proposed JFET stage is calculated by: Av = 0.5 * Rd / Rs. Replacing the optimal values for Rd and Rs gain can be also expressed as: Av = 0.54 * (Vcc/ Vp - 2) Some remarks on the gain formulae are: Rd must be greater than twice Rs or the gain will be less than unity. Vcc must be approximately greater than 4* Vp or the gain will ...
