Abstract
Exemplary embodiments are directed to systems, devices, and methods for enhancing a telescopic amplifier. An amplifier may include a differential pair of input transistors including at least one transistor configured to receive a first input and at least one other transistor configured to receive a second input. The amplifier may further include a cascode circuit including a first pair of transistors coupled to the at least one transistor of the differential pair to form a first plurality of current paths configured to generate a first output. The cascode circuit may also include a second pair of transistors coupled to the at least one other transistor of the differential pair to form a second plurality of currents paths configured to generate a second output.
