Abstract

The limitations of empiric design methods for amplifier biasing stability were pointed out. Critical bias and output range of voltage divider biasing amplifier were discussed. The relationship between bias temperature coefficient and β temperature coefficient was discussed as well. The ratio of bias temperature coefficient to β temperature coefficient is defined as effecting factor. Amplifier bias stability is designed based on output range temperature coefficient. The methods for designing base biasing resistance of voltage divider biasing amplifier on the basis of output range temperature coefficient and for analyzing biasing stability of this amplifier are introduced.
