Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
To address this issue, this paper proposes a capacitor-current-feedback active damping with reduced computation delay, which is achieved by shifting the capacitor current sampling instant towards the PWM reference update instant.
This paper intensively studies the proposed solution using capacitor current ramp compensation, which is a superior solution featuring fast response and universality. A frequency-domain small-signal model based on describing function method is proposed in this paper. The time-domain large-signal response to the load step change is analyzed.
Tighter line and load regulation, low quiescent current operation, capacitor-free and wide-range output capac itor specifications are some of the contradicting requirements in an which drive newer topologies and newer frequency compensation techniques. The objective of this paper is to provide LDO,
Similarly a voltage or current bufer can be placed in series with the Miller capacitor in order to move the RHP zero to the LHP , as described below. Current bufers can be loosely classified as non-inverting or inverting.
Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero. Miller with a nulling resistor. Similar to Miller but with an added series resistance to gain control over the RHP zero.
