摘要：The design and fabrication of a high speed, 12-channel monolithic integrated CMOS optoelectronic integrated circuit （OEIC） receiver are reported. Each channel of the receiver consists of a photodetector, a transimpedance amplifier,and a post-amplifier. The double photodiode structure speeds up the receiver but hinders responsivity. The adoption of active inductors in the TIA circuit extends the - 3dB bandwidth to a higher level. The receiver has been realized in a CSMC 0.6μm standard CMOS process. The measured results show that a single channel of the receiver is able to work at bit rates of 0.8- 1.4Gb/s. Altogether, the 12-channel OEIC receiver chip can be operated at 15Gb/s.

摘要：A multiplexer with a low-distortion high-bandwidth analog switch is presented. The gate-to-source voltage of the switch is set by the combined on-voltage of a pMOS and an nMOS,and the difference between its gate-source voltage and the threshold voltage （VGST） is guaranteed to be constant with input variation. Thus, the body effect is nearly canceled. Implemented in a TSMC 0.18μm CMOS process, results from HSPICE simulation show that the VGST is nearly constant with an input range from 0.3 to 1.7V,and the - 3dB bandwidth is larger than 10GHz;the SFDR （spurious free dynamic range） of the output is 67. lldB with 1GHz input frequency; the turn-on time is 2.98ns,and the turn-off time is 1.35ns, which indicates a break-before-make action of the multiplexer. The proposed structure can be applied to high speed signal transmission.
