Small‐Signal Analysis PNP BJT Small‐Signal Model • The small‐signal model for a PNP transistor is identical to that of an NPN transistor. – Note that the polarity of the small‐signal currents and voltages are defined to be in the opposite direction with respect to the large‐signal model. FET SMALL SIGNAL ANALYSIS Introduction: Field-effect transistor amplifiers provide an excellent voltage gain with the added feature of high input impedance. They are also considered low-power consumption configurations with good frequency range and minimal size and weight. Both JFET and depletion MOSFET devices can be used to designSPICE combined operating point solutions, transient analysis, and various small-signal analyses with the circuit elements and device models needed to successfully simulate many circuits. Analyses. SPICE2 includes these analyses: AC analysis (linear small-signal frequency domain analysis) DC analysis (nonlinear quiescent point calculation)gm CHAPTER FET Small-Signal Analysis 9 9.1 INTRODUCTION Field-effect transistor amplifiers provide an excellent voltage gain with the added fea- ture of a high input impedance. They are also considered low-power consumption configurations with good frequency range and minimal size and weight.

Let’s perform a small-signal analysis to determine an approximate relationship between i c and v BE. Note that the value of v BE BE be ()tV vt= + is always very close to the D.C. voltage for all time t (since v be ()t is very small). We therefore will use this D.C. voltage as the evaluation point (i.e., bias point) for our small-signal analysis. The AC analysis, called a small-signal analysis, can be performed with the dc source set to zero. The total response of the amplifier circuit is the sum of the two individual responses. Large signal amplifiers (or power amplifiers) involve large signal analysis or operation which should include non linearities and is more accurate in …Small‐signal analysis circuit for determiningoutputresistance R out D in v m D n ox D D R R R I R L W A g R C 2 , out Common‐Source Stage: 0 • Channel‐length modulation results in reduced small‐signal voltage gain and amplifier output resistance.
