Abstract :
We present circuits for efficient repeaterless on-chip wires. A transmitter sends RZ pulses to a clockless hysteresis receiver using a 3-tap FIR filter to control ISI. Partly overlapped bits double bandwidth using adaptive pre-emphasis. A 90 nm CMOS testchip shows bandwidth density of 4.4 Gb/s/¿m over 5 mm on-chip links with 0.34 pJ/b energy consumption.
