Abstract:
Devices and methods for finite impulse response (FIR) feed forward equalization (FFE) at a transmitter are provided. A voltage-mode driver circuit has a main driver and an equalization driver. The main driver drives the digital output signal based on a received digital input signal. The equalization function of the equalization driver is enabled or disabled for a short duration of time to provide at least one of FIR equalization and pre-emphasis to the digital output signal. Pre-emphasis is effected by enabling a low-resistance path of the equalization driver based on the digital input signal such that, when the low-resistance path is enabled, it reduces the transmission resistance for a short period of time.

Claim (Index 9):
The transmitter driver circuit of  claim 1 , wherein:\n the equalization driver provides equalization to the digital output signal based on a first data signal and a second data signal, the first data signal and the second data signal each having a disabling value and an enabling value; the variable-resistance path switches between a baseline resistance in response to disabling values of the first and second signals and a low resistance in response to an enabling value of the first or second signal; and the equalization driver further comprises a power source for:\n providing positive polarity signal gain to the digital output signal via the variable-resistance path in response to an enabling value of the first signal; and \n providing negative polarity signal gain to the digital output signal via the variable-resistance path in response to an enabling value of the second signal.
