Abstract
A fast parasitic-insensitive continuous-time filter and equalizer integrated circuit uses an active integrator. The integrator has a left-half plane pole. A feedback path is provided that includes a resistive impedance which comprises a MOS transistor operated in the triode region. The resistive impedance is adjustable for cancelling the pole. The feedback path also includes a capacitive impedance coupled in series with the resistive impedance.
