offset voltage

[′ȯf‚set ‚vōl·tij]
(electronics)
The differential input voltage that must be applied to an operational amplifier to return the zero-frequency output voltage to zero volts, due to device mismatching at the input stage.

Transistor [M.sub.1] which is identical to [M.sub.A1] is used to reduce DC offset voltage between Y and X terminals.
Note that the voltage difference, [DELTA][V.sub.REF] = [V.sub.REF1] - [V.sub.REF2], plays a dominant role in the offset voltage because it is amplified by [1 + 2([R.sub.A]/[R.sub.G])] X ([R.sub.C]/[R.sub.B]).
Here the input offset voltage of 700 millivolt is given as input in order to reduce the noise.
In addition, the dual-Hall element orthogonal coupling and spinning current technology was used to effectively lower the offset voltage. Circuit offset was suppressed using autozeroed technology.
Here, a constant offset voltage is added to the output voltage so that the opamp output will not be saturated to the GND side to maintain a linear characteristic from zero solenoid current.
The nonlinearity indicates the input offset voltage of the single slope ADC.
The resulted input offset voltage can be expressed as
* Packaging in epoxy over-molded ceramic with a heat-conducting alumina substrate that provides low offset voltage of less than 1 [micro]V.
This causes toggling the output voltage polarity, but the offset voltage remains a consistent bias on the output.
Comparison of Fig.2-4 shows that rectenna conversion efficiency for shunt rectifier configuration is independent of offset voltage and is almost constant at any load.
