voltage gain

[′vōl·tij ‚gān]
(electronics)
The difference between the output signal voltage level in decibels and the input signal voltage level in decibels; this value is equal to 20 times the common logarithm of the ratio of the output voltage to the input voltage.

The photodiodes in the trap-detector package were selected with similar shunt resistances to minimize voltage gain for the 1/f input voltage noise and drift of the operational amplifier.
The VGA voltage gain was computed for every 4ms speech signal frame and was converted to bias current ratios as expressed in (8).
NCDR CCDR Voltage gain [V.sub.0]/[V.sub [V.sub.0]/ .sec] = D/2 [V.sub.sec] = 2D/n(1 + n) Output [i.sub.o [i.sub.o current (ripple)] (ripple)] = ripple (1 - 2D) [(1 + n)/ [V.sub.0]/ 2 - 2D] 2L[f.sub.s] [V.sub.0]/2L Diode [MATHEMATICAL [f.sub.s] voltage EXPRESSION [MATHEMATICAL stress NOT EXPRESSION REPRODUCIBLE NOT IN ASCII] REPRODUCIBLE IN ASCII] Peak current [i.sub.sec(peak)] ([V.sub.sec] of [I.sub.0]/2 n[V.sub.0]/ transformer + ([V.sub.sec] [n.sup.2]L) secondary - [V.sub.0] [DT.sub.s] winding /2L)[DT.sub.s] ([n.sub.2]/ [n.sub.1]) [V.sub.0]/L
Cascade of Two Adjustable Voltage Gains in the Loop
The high gain DC-DC converters under consideration are designed for the same voltage gain ratio.
The differential-mode voltage gain and output impedance can be described as:
The second voltage gain stage is a complementary cascode using bipolar Wilson current mirrors.
Finally we note the voltage gain stages are powered from regulated power supplies.
Since the power gain specification is referenced to a 500 [ohms] source and a 5000 [ohms] load, the cascade voltage gain is from -45 to +60 dB.
G(V(t)) = instantaneous input-output envelope voltage gain
while the pass-band voltage gain in the whole frequency range is unity.
