This article proposed a simple self cascode RGC amplifier configuration to increase the gain and bandwidth. The cascode amplifier eliminates the miller capacitance between input and output and facilitates high gain, high input and output impedance with high bandwidth. However, the cascode amplifier requires relatively high supply voltage for proper operation and it decreases the output voltage ...

Low-voltage cascode current mirrors are reviewed with respect to the design limitations imposed if all transistors in the mirror are required to operate in the saturation region. It is found that both a lower limit and an upper limit exist for the cascode transistor bias voltage. Further, the use of a signal dependent cascode bias voltage is discussed and a selfbiased cascode configuration is p...

|A simple cascode circuit with the gate voltage of the cascode transistor being controlled by a feedback ampli er and thus named `regulated cascode' is presented. In comparison to the standard cascode circuit the minimum output voltage is lower by about 30 to 60% while the output conductance and the feedback capacitance are lower by about 100 times. An analytical large-signal, small-signal, and...

A technique is proposed for the design of a modified CMOS regulated cascode having an output impedance significantly greater than that of a conventional regulated cascode. Simulation results for an illustrative design, operating at 10μA from a 1V supply, show an increase in output resistance from 636MΩ and output bandwidth of 55kHz for a conventional circuit to 6.68GΩ and 389kHz, respectively, ...

A fully differential self-biased inverter-based folded cascode amplifier which uses the feedforward-regulated cascode principle is presented. A detailed small-signal analysis covering both the differential-mode and the common-mode paths of the amplifier is provided. Based on these theoretical results a design is given and transistor level simulations validate the theoretical study and also demo...
