A wideband, low-power preamplifier and a high-speed, low-power monolithically integrated regenerative receiver are designed and fabricated using small-scale InP/InGaAs DHBTs. The preamplifier has a gain-bandwidth product of 192 GHz with a power dissipation of 51 mW. The regenerative receiver is successfully operated at 20 Gbit/s with a power dissipation of 0.6 W and an input dynamic range of 13 dB. This IC offers the lowest energy ever reported for regenerative receivers. In addition, a 20-Gbit/s optical modulator driver with a driving voltage of 2 V is successfully fabricated. These results demonstrate the feasibility of InP/InGaAs DHBTs for high-speed, low-power lightwave communication ICs.
