It increases linearly with increasing frequency. B. It decreases linearly with increasing frequency. C. It decreases logarithmically with increasing frequency. D. It does not vary with frequency . E6B14 (A) What essentially determines the output impedance of a FET common-source amplifier? A. The drain resistor. B. The input impedance of the FET. C. High frequency Response of CE Amp.: Millers Theorem NOTE: Common base and common collector amplifiers do not suffer from the Miller effect, since in these amplifiers, one side of is connected directly to ground. When the common base mode is used,the base-collector capacitor does not affect the input since it is grounded at the base end.

AUDIO AMPLIFIERS . An audio amplifier has been described as an amplifier with a Frequency response from 15 Hz to 20 kHz. The Frequency response of an amplifier can be shown graphically with a Frequency response curve. Figure 1-22 is the ideal Frequency response curve for an audio amplifier. This curve is practically "flat" from 15 Hz to 20 kHz. Field Effect Transistor RF Amplifier Design Techniques By: Roy C. Hejhall Applications Engineering Amplifier design theory utilizing the two port network model for an active device has been well developed and used extensively in bipolar transistor high frequency amplifier design. This paper discusses some of the theoretical and However, at the same time, lower reactance means higher almost cancel each other, resulting in a uniform fair at mid-frequency. Common Emitter Amplifier analysis. The first step in AC analysis of Common Emitter amplifier circuit is to draw AC equivalent circuit by reducing all DC sources to zero and shorting all the capacitors. To examine the frequency response of the common-gate amplifier, the input frequency was varied from 1 Hz up to 2.3 MHz, with 9 intermediate frequencies, and data was collected at each of these frequencies. With both the positive and negative poling voltages, the effects of varying the biasing conditions on the FeFET were also obs erved. This
high source impedance and drives the common source amplifier with a low source impedance. A source follower driving a common gate amplifier boosts the input impedance. This is essentially a differential pair driven single-endedly. A common-source amplifier drives a common-gate amplifier, or a cascode amplifier. Miller effect is minimized by ... 1.)
