Miller Capacitor with Wide Input Range and Its Application to PLL Loop Filter

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2006
This paper proposes a Miller capacitor which has a wide input signal range. By discharging the charge of the capacitor connected between the input and output terminals of an amplifier before the output voltage of the amplifier exceeds its maximum range, the amplifier always operates in the active region and the Miller operation can be guaranteed.

A Transient-Enhanced Output-Capacitor-Free Low-Dropout Regulator With Dynamic Miller Compensation

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2019
A transient-enhanced output-capacitor-free low-dropout regulator (LDR) based on dynamic Miller compensation (DMC) is presented in this brief. By utilizing different Miller capacitors to compensate the LDR at different load ranges, the proposed DMC technique can extend the loop bandwidth and enhance the transient performances.

More Accurate Miller Capacitor Modeling for SiC Switching Characteristic Prediction in High Frequency Applications

2019 IEEE 4th International Future Energy Electronics Conference (IFEEC), 2019
A more accurate miller capacitor model is proposed in this paper to achieve precise SiC switching characteristic prediction for high frequency and high power density designs. The SPICE models of power transistors are either not provided or fail to represent parasitic capacitor accurately, which will lead to poor estimation of device switching loss. For

Distortion Modeling of Feedback Two-Stage Amplifier Compensated With Miller Capacitor and Nulling Resistor

IEEE Transactions on Circuits and Systems I: Regular Papers, 2012
Accurate distortion modeling of feedback amplifier with Miller compensation is the main subject of this paper. Inspired by traditional Rosenstark method, a nonlinear signal-flow-based method has been developed. Based on the proposed method, the nonlinear coefficients of each gain stage can be evaluated exactly and the rules of cascading, feedback can ...

A Novel Pre-charge Circuit Using Virtual Miller Capacitor in a Single Phase Rectifier

2018 IEEE Energy Conversion Congress and Exposition (ECCE), 2018
In all the grid connected converters, irrespective of the front end topology (whether it is a diode rectifier, a bridgeless active power factor correction rectifier, or an active front end rectifier (AFE)), there is always a DC bus electrolytic capacitor with high value after the front end, for energy storage and line frequency ripple mitigation ...

A robust feedforward compensation scheme for multistage operational transconductance amplifiers with no Miller capacitors

IEEE Journal of Solid-State Circuits, 2003
A multistage operational transconductance amplifier with a feedforward compensation scheme which does not use Miller capacitors is introduced. The compensation scheme uses the positive phase shift of left-half-plane (LHP) zeroes caused by the feedforward path to cancel the negative phase shift of poles to achieve a good phase margin.

Low-power three-stage amplifier using active-feedback Miller capacitor and serial RC frequency compensation

Transactions of Tianjin University, 2015
A low-power three-stage amplifier for driving large capacitive load is proposed. The feedback path formed by the active-feedback Miller capacitor leads to a high frequency complex-pole but a high Q-value, which significantly deteriorates the stability of the amplifier.
