feedback capacitance การใช้

• A well-known example of this is the Miller effect, in which an unavoidable feedback capacitance appears increased ( i . e . its impedance appears reduced ) by negative feedback.
• In other words, the upper FET exhibits a low input resistance to the lower FET, making the voltage gain of the lower FET very small, which dramatically reduces the Miller feedback capacitance from the lower FET's drain to gate.
