Supply independent biasing circuit
WebDepending on the supply voltage, typical values that provide a reasonable compromise between increased supply current and increased sensitivity to amplifier bias current, range from 100 k ohms for +15-V or +12-V single supplies, down to 42 k ohms for a 5-V supply and 27 k ohms for 3.3 V. WebCircuit performance is evaluated by means of hand calculations and computer simulations. The course begins with a review of bipolar and MOS transistors operation, followed by the study of dc and ac properties of single-stage and multistage amplifiers. ... supply and temperature independent biasing is examined.
