: ※ 引述《[email protected] (BME新生)》之銘言:
: > BJT特性有容易受溫度變化
: > MOS參數中無溫度變化係數,故較不易受環境影響
: 同是矽材料, PN 的接面, 溫度影響不可免.
: 影響有多大? 電路可抵消, 書中自有答案說.
In silicon, BJT has higher transconductance and an ability to build temperture
independant reference; MOSFET has better linearity and lower power dissipation
in digital circuits which helps to integrated as a mixed signal chip.
