To analyze multistage amplifier the h-parameters of the transistor used are obtained from manufacturer data sheet. In this case, overall current gain A IS is defined as The ratio of output voltage to input voltage gives the gain of the transistors.Ī v is the voltage gain for an ideal voltage source (R v = 0).Ĭonsider input source to be a current source I S in parallel with a resistance R S as shown in fig. The impedance looking into the amplifier input terminals ( 1,1' ) is the input impedance Z i The quantities of interest are the current gain, input impedance, voltage gain, and output impedance.įor the transistor amplifier stage, A i is defined as the ratio of output to input currents. (Phasor notations are used assuming sinusoidal voltage input). The ac equivalent circuit is shown in fig. The h-parameters are assumed to be constant over the operating range. R S is the source resistance and Z L is the load impedance. 1 and to bias the transistor properly.Ĭonsider the two-port network of CE amplifier. To form a transistor amplifier it is only necessary to connect an external load and signal source as indicated in fig. It does not store any personal data.ANALYSIS OF A TRANSISTOR AMPLIFIER USING H-PARAMETERS: The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies.
