MULTISTAGE AMPLIFIER WITH HYBRID NESTED MILLER COMPENSATION |
摘要 |
A high frequency amplifier arrangement using hybrid nested Miller compensation (HNMC) as a means to frequency compensate amplifiers. The arrangement comprises four amplifier stages, or any other even number higher than four. Each of the four stages can be inverting or balanced pair stages. The Miller compensation is provided by capacitors connected across the output and input of several of the stages, and with a third capacitor connected across the other stages. The HNMC circuit allows the use of lower supply voltages, consumes less supply power, and avoids the need to drive the output transistor with a differential stage. Other variations employ a multipath input stage, and opamps comprising 6 and 8 stages are also described. |
