In this paper, we designed a multichannel transceiver for high-speed optical interconnect applications. The proposed multichannel transceiver is designed in 0.13 mu m CMOS technology. The multichannel transceiver consists of 4-channel transmitter (Tx) and 4-channel receiver (Rx). The simulated Tx has a 3-dB BW of 5.85 GHz with a voltage gain of 35 dB and the measured 3-dB BW is 5.20 GHz. The simulated Rx has the 3-dB BW of 5.95 GHz with a transimpedance gain of 80 dB Omega and the measured 3-dB BW of Rx is 5.25 GHz. To improve frequency operation of Rx, transimpedance amplifier (TIA) active feedback has been applied. Utilization of an active feedback in TIA significantly improves the frequency operation, where 3-dB BW has been improved from 3.27 to 11 GHz with transimpedance gain of 65 dB Omega. Furthermore, to improve the output light of performance temperature sensing circuit has also been integrated in the same silicon substrate with transceiver chip to provide stable output light power temperature range of -30 similar to 100 degrees C
