A 5 VPP Differential Output Swing MZI Driver Amplifier in 65 nm CMOS for Optoelectronic Applications
Keywords:
Mach Zehnder Interferometric (MZI) modulator based optical communication systems are finding increased research interests. With the rapid scaling of technology, obtaining higher output swing required for driving the MZI modulator has become increasingly challenging. To address this issue, this paper demonstrates a driver amplifier for the MZI modulator with a 5 VPP differential swing in 65nm CMOS. Post layout simulation results show that for 5 Gb/s data rate, the driver consumes 308 mW from a 4 V power supply, which is significantly less power consumption compared to previously reported MZI modulator drivers. Simulation results also confirm the driver operation at 10 Gb/s.Abstract
Mach Zehnder Interferometric (MZI) modulator
based optical communication systems are finding increased
research interests. With the rapid scaling of technology,
obtaining higher output swing required for driving the MZI
modulator has become increasingly challenging. To address this
issue, this paper demonstrates a driver amplifier for the MZI
modulator with a 5 VPP differential swing in 65nm CMOS. Post
layout simulation results show that for 5 Gb/s data rate, the
driver consumes 308 mW from a 4 V power supply, which is
significantly less power consumption compared to previously
reported MZI modulator drivers. Simulation results also
confirm the driver operation at 10 Gb/s.
