Q. Why negative feedback is employed in Wein Bridge Oscillator. Also explain the working of oscillator?
The Wein Bridge Oscillator consists of two stages of the RC coupled amplifier and a feedback network. The block diagram given in figure explain the principle of working of this oscillator. Here the two blocks are A1 and A2. These two represents two amplifier stages. The output of the second stage goes to the feedback network. The voltage across the parallel combination C2R2 is fed to the input of the first stage. First amplifier stages produce 1800 phase shift and the second amplifier also provides 1800 phase shift. Total phase shift is 3600 Therefore it is evident that for the oscillation to be maintained, the phase shift through the coupling network must be zero. It can be shown that this condition occurs at a frequency given by
Q. D flip-flop - latch or delay element? The symbol for the clocked D flip-flop is shown in Figure (a), in which the two output terminals Q and ¯ Q behave just as in the SRFF,

Analysis Flow Similar to most subjects, the analysis of semiconductor devices is also performed by starting from simpler problems and regularly progressing to more complex one
What is Capacitance - Capacitance is explained to be the amount of charge Q stored in among the two plates for a potential difference or voltage V existing across the plates.
