What is quiescent state?
Definition. Quiescence is the reversible state of a cell in which it does not divide but retains the ability to re-enter cell proliferation. Some adult stem cells are maintained in a quiescent state and can be rapidly activated when stimulated, for example by injury to the tissue in which they reside.
What is meant by quiescent condition?
Quiescent: Inactive, resting. For example, tuberculosis can be a quiescent (inactive) infection.
What is the quiescent state of an amplifier?
The operating point of a device, also known as bias point, quiescent point, or Q-point, is the DC voltage or current at a specified terminal of an active device (a transistor or vacuum tube) with no input signal applied. A bias circuit is a portion of the device’s circuit which supplies this steady current or voltage.
What is quiescent state of transistor?
Quiescent means “at rest”. In a transistor circuit, the quiescent state is defined by the voltages and currents present in the circuit when the power supply is on and stable, and no signal is applied.
What does quiescence mean?
adjective. being at rest; quiet; still; inactive or motionless: a quiescent mind.
What does quiescent mean in electronics?
Glossary Term: Quiescent Definition. For an electronic circuit, a quiet state in which the circuit is driving no load and its inputs are not cycling. Most commonly used for the specification “quiescent current,” the current consumed by a circuit when it in a quiescent state.
What is quiescent operating point in electronics?
Q point or the operating point of a device, also known as a bias point, or quiescent point is the steady-state DC voltage or current at a specified terminal of an active device such as a diode or transistor with no input signal applied.
What is quiescent load?
Quiescent load is the power requirement of a piece of equipment which is idle, listening or monitoring. Transceivers generally have different load profiles when transmitting and when listening.
What is quiescent point or Q point?
The operating point of a device, also known as a bias point, quiescent point or Q-point, is the steady-state DC voltage or current at a specified terminal of an active device such as a transistor with no input signal applied. If a transistor’s junction temperature is allowed to increase, thermal runaway may occur.
What is the quiescent zone?
The quiescent zone, defined as regions of cells which did not display DNA synthesis 24 hours after planting, included stelar initials, columella and adjacent surrounding cells. In effect, the stelar and columella regions appear to be connected with non-DNA synthesizing cells of the root cap.
Why quiescent centre is important?
It is a region in the apical meristem of a root where cell division proceeds very slowly or not at all, but the cells are capable of resuming meristematic activity when the tissue surrounding them is damaged. Such a quiescent centre includes the cells at the apices of the histogens of both stele and cortex.
What is the definition of a quiescent current?
Definition of Quiescent current from Maxim: For an electronic circuit, a quiet state in which the circuit is driving no load and its inputs are not cycling. Most commonly used for the specification “quiescent current,” the current consumed by a circuit when it in a quiescent state.
What’s the difference between quiescent and shutdown current?
Quiescent is defined as “a state or period of inactivity or dormancy.” Thus, quiescent current, or IQ, is the current drawn by a system in standby mode with light or no load. Quiescent current is commonly confused with shutdown current, which is the current drawn when a device is turned off but the battery is still connected to the system.
What does quiescent power mean in a LDO?
Quiescent power (also called static power) is the power drawn by the device when it is powered up, configured with user logic and there is no switching activity from NXPfor an LDO: Quiescent or ground current, is the difference between input and output current. It describes the current which the LDO consumes by itself.
Which is the correct definition of the quiescent point?
The Quiescent Point is also known as the operating point. Typically the Q-point is chosen by the designer for a specific application. The point basically represents the allowed devices voltages and currents.
