v] represents the static voltage gain
of the proposed CWVM converter.
The unity voltage gain
output stage begins with a highly linear common-emitter-common-collector compound pair followed by emitter-follower transistors connected to the speakers.
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.
Of course, this is a $300 receiver, so only one emitter follower buffers the second voltage gain
stage from the output device.
8 [micro]V/[degrees]C times the dc voltage gain
In prior articles, I have yammered about the need to isolate the differential pair from the second voltage gain
stage to ensure low distortion, especially at 20 kHz.
The AS1713 offers a fixed differential voltage gain
Rockford's patented Trans-nova technology provides voltage and current gain at the output state (power gain), unlike other amplifier designs that use "buffers" following voltage gain
stages, killing current gain and requiring more parts that result in more noise and distortion.
The operational amplifier that is driven differentially from the DAC uses a single voltage gain
stage, called a folded cascode, to provide wide bandwidth and good settling time.
This circuit automatically adjusts the voltage gain
and pass-band frequency response of the input receiver to compensate for signal loss (attenuation) and distortion over the system's internal distribution path.
Finally we note the voltage gain
stages are powered from regulated power supplies.
The growing trend of digital power management, with the use of standard microcontroller in motor control, power supply, and PFC circuits require the interface, voltage gain
and drive of the IXI858/859 for digital power management.
