English: Block diagram of an electronic oscillator circuit, with the feedback loop broken to show how to calculate the loop gain. It consists of an amplifier element with amplification A, with its output V o fed back into its input V i through a feedback network with transfer function β(jω).
Oscillator block diagram.svg is the same image with A and β(jω) replaced with alternate variables G(jω) and H(jω). Oscillator diagram2.svg is the same image with the feedback loop shown broken, to show how loop gain is calculated.
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
English: Block diagram of a negative resistance electronic oscillator, illustrating the "reference plane" analysis method.The circuit consists of a differential negative resistance device such as a Gunn diode or magnetron tube connected to a resonator such as a LC circuit, dielectric resonator, or cavity resonator.
b-c: The charge from the capacitor begins to flow through the bulb, instantly increasing the current to point b in the "abnormal glow" region of the curve. The bulb turns on. c-d: The voltage across the bulb and capacitor drops quickly to the extinguishing voltage V e at which the voltage is insufficient to continue ionizing the gas. The bulb ...

Basis of solid-state Blocking oscillator The waveform generated by this circuit This Joule thief circuit, a blocking oscillator, can be used in order to power a light-emitting diode from a 1.5V battery for a relatively long period of time, with the brightness being a tradeoff.
