Bias circuitry failure causes transistor operating points to shift, resulting in distorted output signals, reduced gain, increased noise, thermal runaway, or complete circuit malfunction.
Temperature changes alter semiconductor properties, causing bias voltages and currents to drift. Quality bias circuits incorporate temperature compensation using bandgap references or proportional-to-absolute-temperature (PTAT) circuits to maintain stability.
