Abstract
Systems and methods are disclosed to adaptively generate coefficients for continuous time least mean square error equalizers and to correct offset in high-gain amplifiers. An adaptive coefficient generator includes a bank of individual coefficient generators, each utilizing a first adaptive correction signal for a first correction and a second adaptive correction signal for a second more precise correction. The adaptive correction signals for offset correction can be a current or voltage. The first adaptive correction signal is set by maintaining the second adaptive correction signal constant, such as setting it to zero, and adjusting the first signal until the magnitude of the coefficient is minimized. The second adaptive correction signal is then set by maintaining the first adaptive correction signal at its set value by adjusting the second signal until the magnitude of the coefficient is again minimized.
