WebBy setting this voltage at 5 volts, variations as much as +/- 3 Volts can appear on the Drain of Q3 before the voltage across Q3 dips below 2 volts and distortion sets in. If you are running the amplifier with balanced inputs, then this voltage can be set lower, as the variation at the drain of Q3 will only be a volt or so. Web3 mei 2012 · Compensation for offset voltage (a) using a parallel external resistor, (b) using a series external resistor. For example, if RB = 5 kΩ and β = 0.02, we have RP = 250 kΩ. Compensation can also be made using a series scheme. A small resistor Rs = β RB is connected in series with resistor R1, as shown in Fig. 6.11 (b).
