High-speed current-mirror circuitry and method of operating the same |
摘要 |
There is disclosed high-speed current-mirror circuitry and methods of operating the same. An exemplary impedance-peaking current mirror comprises a N-channel drive transistor and a N-channel mirror transistor. The N-channel drive transistor has a source coupled to ground, a drain coupled to a current source and a gate coupled to the drain via a series connection of a resistor and an inductor. The N-channel mirror transistor has a source coupled to ground, a gate coupled to the drain of the N-channel drive transistor, and a drain coupled to a positive power supply via an impedance load.
