Click to expand Folded Cascoded Amplifier Advantages: 1. High Gain 2. Improved Bandwidth 3. High Slew rate 4. High stability 5. High input impedance 6. The folded cascode Opamp is useful for moderately low supply voltages, at the cost of some extra current, but has limited performance in sub 1V applications, as well as a limited Vcm in. Telescopic Amplifier Advantages Usually provides best trade off between 1. Gain 2. Power dissipation 3.

Speed 4. Noise 5. Higher Frequency Capability Disadvantages 1. Output swing is limited and shorting input and output is difficult.
