The transmitter consists of a pulser which is based on the ON/OFF operation of an LC oscillator. Fabricated in 0.18-mum CMOS technology with 1.5 V supply, measurements show the FCC-compliant output pulses with the duration of 3.5 ns, which corresponds to 520 MHz bandwidth. Maximum pulse rate is up to over 200 MHz. The pulser dissipates only the dynamic current with average energy of 16.8 pJ per pulse, and the receiver dissipates 3.5 mA of static current.

In order to obtain the precise output current without suffering from poor current mismatch in a bit-block, the input and output currents in a current-mirror circuit are exchanged at every clock period. This produces signal currents at the output of a bit-block with positive and negative mismatch errors in turn. Since the analog-to-digital (A-D) converted digital codes of a bit-block contain these positive and negative mismatch errors, the errors are canceled out by taking the average of the consecutive digital codes at the output part of the ADC. A current-mode ADC using this proposed scheme has been fabricated by using 0.25 mum CMOS devices.
