Abstract	A 4-level pulse amplitude modulation (PAM-4) silicon photonic transmitter targeting operation at 25 Gb/s is designed using an electrical-photonic co-design methodology. The prototype consists of an electrical circuit and a photonics circuit, which were designed in 130 nm IBM SiGe BiCMOS process and 130nm IME SOI CMOS process, respectively. Then the two parts will be interfaced via side-by-side wire bonding. The electrical die mainly includes a 12.5 GHz PLL, a full-rate 4-channel uncorrelated $2^{7}$ - 1 pseudo-random binary sequence (PRBS) generator and CML drivers. The photonics die is a 2-segment Mach-Zehnder modulator (MZM) silicon photonics device with thermal tuning feature for PAM-4. Verilog-A model for the MZM entails the system simulation for optical devices together with electrical circuitry using custom IC design tools. A full-rate 4-channel uncorrelated PRBS design using transition matrix method is detailed, in which any two of the 4-channels can be used for providing random binary sequence to drive the two segments of the MZM to generate the PAM-4 signal.
