Stagger Tuned Amplifier – Circuit diagram and its Workings

Stagger Tuned Amplifier – Circuit diagram and its Workings: In order to increase bandwidth, double tuned amplifiers are preferred, but their alignment is difficult. A much better overall response can be had by stagger tuning, as illustrated in Fig. 18.22. If two or more tuned circuits are cascaded and tuned to the same frequency, it …

Large Signal Tuned Amplifier – Operation and its Equivalent Circuit

Large Signal Tuned Amplifier – Operation and its Equivalent Circuit: Tuned amplifier circuits are for class A operation and their use is limited to applications in which RF signal has low power levels such as in radio receivers. Such amplifiers are not suitable for applications involving larger RF power, because of lower efficiency of class …

Double Tuned Amplifier – Circuit Diagram and Operation

Double Tuned Amplifier – Circuit Diagram and Operation: The problem of potential instability with a single tuned amplifier is overcome in a double tuned amplifier which consists of inductively coupled two tuned circuits—one (L1, C1) in the collector circuit and the other (L2, C2) in the output circuit, as shown in Fig. 18.12. A change …

Tuned Amplifiers – Definition, Classification and Advantages

Tuned Amplifiers – Definition, Classification and Advantages: Amplifier amplifying a signal of specific frequency or narrowband of frequencies is known as tuned amplifier. Tuned amplifiers are mostly employed for amplification of high or radio frequency signals, because radio frequencies are generally single and tuned circuits permit their selection. Such amplifiers cannot be used for amplification …
