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.
Do, "A soft-switching dc/dc converter with high voltage gain
", IEEE Trans.
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
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.
