Referring to Figure 10, both inputs are terminated in their
characteristic impedance; 75
is typical for video
applications. Since the drivers usually are terminated in their
characteristic impedance the input gain is 0.5, thus the
amplifiers, U2, are configured in a gain of +2 to set the circuit
gain equal to one. Resistors R2 and R3 determine the amplifier
gain, and if a different gain is desired R2 should be changed
according to the equation G = (1 + R3/R2). R3 sets the
frequency response of the amplifier so you should refer to the
manufacturers data sheet before changing its value. R5, C1
and D1 are an asymmetrical charge/discharge time circuit
which configures U1 as a break before make switch to prevent
both amplifiers from being active simultaneously. If this design
is extended to more channels the drive logic must be designed
to be break before make. R4 is enclosed in the feedback
loop of the amplifier so that the large open loop amplifier
gain of U2 will present the load with a small closed loop
output impedance while keeping the amplifier stable for all
values of load capacitance.
The circuit shown in Figure 10 was tested for the full range of
capacitor values with no oscillations being observed; thus,
problem one has been solved.The frequency and gain
characteristics of the circuit are now those of the amplifier
independent of any multiplexing action; thus, problem two
has been solved. The multiplexer transition time is
approximately 15
s with the component values shown.
