Booster Preamplifiers SAR4, SARS
resistor 1Rl4 is added to roll off of the high fre-
quency response above 15 kc.
As shown in figure 6, this amplifier is similar to
the one shown above. Since no switching is per-
formed in the output, the second output capacitor
le6 and shunt resistor 1R13 are omitted. A series
