The two resistors form a voltage divider to produce a control voltage Vc = Vs * (Rc / (Rc + Rs)) where Vc is the returned control voltage, Vs is the source voltage, Rc is the variable control resistance, and Rs is the source resistance. Vs may be greater than 10 V so that a maximum intended value of Rc produces a 10 V maximum control voltage.
Open drain output uses MOS transistor (MOSFET) instead of BJTs, and expose the MOSFET's drain as output. [ 1 ] : 488ff An nMOS open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate.
The output part of the simple current mirror is an example of such a current source widely used in integrated circuits. The common base , common gate and common grid configurations can serve as constant current sources as well.
This equation implies that any emerging or disappearing amount of flow in a given volume must have a source or a sink, respectively. Sources represent locations where fluid is added to the region of space, and sinks represent points of removal of fluid. The term is positive for a source and negative for a sink. [1]
Depending on the source of current for the loop, devices may be classified as active (supplying or "sourcing" power) or passive (relying on or "sinking" loop power). For example, a chart recorder may provide loop power to a pressure transmitter. The pressure transmitter modulates the current on the loop to send the signal to the strip chart ...
The source measure unit (SMU), or source-measurement unit, is an electronic instrument that is capable of both sourcing and measuring at the same time. It can precisely force voltage or current and simultaneously measure precise voltage and/or current. An SMU instrument can source and sink power in all four quadrants.
A 14-year-old boy is in a serious condition in hospital following a stabbing in the West Midlands. Police said they were called to Brunel Road, Oldbury, in the early hours, after he was found with ...
In electronics, a high output would mean the output is sourcing current from the positive power terminal (positive voltage). A low output would mean the output is sinking current to the negative power terminal (zero voltage). High impedance would mean that the output is effectively disconnected from the circuit.
