High speed amplifier

摘要

A circuit may include one or more transistors connected directly to an output, and an inductance network. The inductance network may connect to a source node of at least one of the transistors, to compensate capacitance of the output. Thus, the response time of the circuit may decrease, and a non-dominant frequency response pole frequency of the circuit may increase.

1. A circuit, comprising:
one or more transistors connected directly to an output node; and an inductance network connected to a source node of at least one of the transistors, wherein
an inductance L of the inductance network is based on a transconductance gm of the circuit and a capacitance C at the output node, andthe inductance network compensates the capacitance C at the output node,wherein the inductance L is determined according to L=kC/gm2, k being a constant.
