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.
The nonlinearity indicates the input offset voltage of the single slope ADC.
The resulted input offset voltage can be expressed as
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.
