发明名称 Three stage amplifier
摘要 A cascaded amplifier including a pre-amplifier stage having a pair of first transistors, each of the first transistors having a first gate terminal coupled to a first input voltage, a trans-conductive (gm) amplifier stage having a pair of second transistors, each of the second transistors having a second gate terminal coupled to a drain terminal of one of the first transistors, and an integrator amplifier stage having a pair of third transistors, each of the third transistors having a third gate terminal coupled to a drain node of one of the second transistors, each of the third transistors having their drain terminals coupled to an output voltage.

主权项 1. A cascaded amplifier arranged in a closed-loop configuration, comprising: a pre-amplifier stage having a pair of first transistors, each of the first transistors having a first gate terminal coupled to a first input voltage; a trans-conductive (gm) amplifier stage having a pair of second transistors, each of the second transistors having a second gate terminal directly connected to a drain terminal of one of the first transistors; and an integrator amplifier stage having a pair of third transistors, each of the third transistors having a third gate terminal directly connected to a drain node of one of the second transistors, each of the third transistors having their drain terminals coupled to an output voltage.
