| Popis: | This paper presents a method of biasing high gain ring amplifiers with cascoded output stages while retaining the high slew capability of the ring amplifier. The proposed method biases all devices in the output stage using voltages from the previous stage made available by a resistor ladder. Transistor level simulations of a ring amplifier in a 65nm CMOS process are presented showing 80dB settling accuracy within 2ns. The design is used in a switched capacitor amplification configuration with a closed loop gain of 64. |
