Cascode Amplifiers
A cascode amplifier is a single-stage amplifier circuit that combines the signal input and output pins of a transistor into a single output pin. This can be achieved using a single resistor connected between the input and output pins.
Folded-Cascode Amplifiers
A folded-cascode amplifier is a cascode amplifier that uses a second transistor to drive the first transistor's gate. This allows the second transistor to control the gain and bandwidth of the first transistor. Folded-cascode amplifiers can achieve higher gains than single-stage cascode amplifiers, but they are also more complex and expensive to design
