  2. Frequency divider - Wikipedia

    en.wikipedia.org/wiki/Frequency_divider

    A frequency divider, also called a clock divider or scaler or prescaler, is a circuit that takes an input signal of a frequency, , and generates an output signal of a frequency: f o u t = f i n N {\displaystyle f_{out}={\frac {f_{in}}{N}}}

  3. Pole splitting - Wikipedia

    en.wikipedia.org/wiki/Pole_splitting

    Pole splitting is a phenomenon exploited in some forms of frequency compensation used in an electronic amplifier.When a capacitor is introduced between the input and output sides of the amplifier with the intention of moving the pole lowest in frequency (usually an input pole) to lower frequencies, pole splitting causes the pole next in frequency (usually an output pole) to move to a higher ...

  5. Miller theorem - Wikipedia

    en.wikipedia.org/wiki/Miller_theorem

    Frequency compensation for general purpose operational amplifiers and transistor Miller integrator are examples of useful usage of the Miller effect. The op-amp inverting amplifier is a typical circuit, with parallel negative feedback, based on the Miller theorem, where the op-amp differential input impedance is apparently decreased to zero

  6. Relaxation oscillator - Wikipedia

    en.wikipedia.org/wiki/Relaxation_oscillator

    Relaxation oscillators are generally used to produce low frequency signals for such applications as blinking lights and electronic beepers. During the vacuum tube era they were used as oscillators in electronic organs and horizontal deflection circuits and time bases for CRT oscilloscopes; one of the most common was the Miller integrator circuit invented by Alan Blumlein, which used vacuum ...

  7. Power dividers and directional couplers - Wikipedia

    en.wikipedia.org/wiki/Power_dividers_and...

    Although a negative quantity, the minus sign is frequently dropped (but still implied) in running text and diagrams and a few authors [4] go so far as to define it as a positive quantity. Coupling is not constant, but varies with frequency. While different designs may reduce the variance, a perfectly flat coupler theoretically cannot be built.

  8. Frequency-division multiplexing - Wikipedia

    en.wikipedia.org/wiki/Frequency-division...

    At the source end, for each frequency channel, an electronic oscillator generates a carrier signal, a steady oscillating waveform at a single frequency that serves to "carry" information. The carrier is much higher in frequency than the baseband signal. The carrier signal and the baseband signal are combined in a modulator circuit.

  9. Miller effect - Wikipedia

    en.wikipedia.org/wiki/Miller_effect

    In analog amplifiers this curtailment of frequency response is a major implication of the Miller effect. In this example, the frequency ω 3dB such that ω 3dB C M R A = 1 marks the end of the low-frequency response region and sets the bandwidth or cutoff frequency of the amplifier.
