bypass capacitor
A bypass capacitor is connected across the power supply pins of the integrated circuit.
Noun: A bypass capacitor is a capacitor designed to provide a low-impedance path for alternating current (AC) signals, particularly high-frequency noise or unwanted signals, to ground. This allows it to "bypass" these signals away from a specific part of a circuit, thereby stabilizing the voltage for other components.
The term is used specifically in electronics and electrical engineering to describe a component's function in a circuit. It is a technical compound noun. * A bypass capacitor is typically placed close to an integrated circuit's power pins. * The primary role of a bypass capacitor is to filter out high-frequency noise.
- Noun:
- You should add a bypass capacitor between the VCC and GND pins to reduce voltage spikes.
- The effectiveness of a bypass capacitor depends on its placement and capacitance value.
- High-frequency noise was eliminated by installing a small bypass capacitor.
- "to bypass a signal": This verbal phrase describes the action that a bypass capacitor performs. The capacitor itself is the component that accomplishes this.
- The capacitor helps bypass switching noise to the ground plane.
- Decoupling capacitor: (Noun) A very closely related term often used interchangeably with "bypass capacitor," though subtle distinctions in function (isolating circuit segments vs. providing a local charge reservoir) are sometimes made by engineers.
- Bypass condenser: (Noun) An older, less common term for the same component.
- Decoupling capacitor: (Noun) The most direct synonym in circuit design.
- Shunt capacitor: (Noun) A more general term for a capacitor that provides an alternative path to ground.
- Power supply filtering: (Noun Phrase) This is the general purpose a bypass capacitor serves.
- High-frequency bypass: (Noun Phrase) Describes the specific function of shunting high-frequency signals.
