Abstract
A linear equalizer (LEQ) includes a first transconductance device coupled to an input node of the LEQ and a second transconductance device AC coupled to the input node of the LEQ to increase a gain of the LEQ for data signals above a predetermined frequency. The first transconductance device and the second transconductance device are of complimentary types. A bimodal LEQ includes inputs to control operation of the bimodal LEQ in a current mode or a voltage mode. The bimodal LEQ includes first and second transconductance devices. One of the first and second transconductance devices is AC coupled to an input node to increase the gain for data signals above a predetermined frequency.
