== Phase Compensation == |
|||
Phase compensation is the correction of phase error(i.e., the difference between the actually needed <br />phase and the obtained phase). A phase compensation is required to obtain stability in an opamp.<br /> A capacitor/RC network is usually used in the phase compensation to keep a phase margin. <br /> A phase compensator subtract out an amount of phase shift from a signal which is equal to the <br /> amount of phase shift added by switching one or more additional amplifier stages into the <br /> amplification signal path. |
