The high voltage gain
and low the voltage stress of devices which makes Micro Converter efficient.
We see a progression of output voltage gain
in Figure 8.
Gone are the buffer between the first and second gain stages, the complementary second voltage gain
stage, and the cascode in the first voltage gain
v] and the constitutive relations of the h-parameters, Equation 3, the voltage gain
o] is the dc open loop voltage gain
in V/V, and [tau] is the time constant of the dominant pole of the amplifier in s.
Gain [-] (typical) Bandwidth [MHz] (minimal) Voltage gain
The boost converters with coupled inductor are the preeminent solution that ensures high voltage gain
while the switch works with low duty ratio [12-14].
For example, you can directly evaluate the circuit's voltage gain
and input impedance.
The second voltage gain
stage of the power amp is fully complementary.
The voltage gain
is then 1/[square root of (8)] and the power gain is 1/8.
The closed loop voltage gain
is equal to the reciprocal of the feedback attenuation of the converter if the loop gain is high enough .
Providing a fixed voltage gain
of 25 are the ZXCT1084 and ZXCT1085, while for the ZXCT1086 and ZXCT1087 the gain is 50.
