Abstract
A Mach-Zehnder modulator (MZM) driver is designed in a 22 nm FDSOI-CMOS technology. The high-voltage driving of the MZM is realized with stacked, low- impedance and loss switches which allow a voltage swing that reaches a multiple of the breakdown voltage of a single transistor. In order to use this topology the signal is transferred to the different voltage domains with level-shifters, then amplified and conditioned to rail-to-rail swing which drives the output power-stages. Shunt- and series inductive peaking is used extensively in order to increase the bandwidth. Stacking and coupling inductors results in the smallest MZM driver with 0.018 mm2 active area. Measurements show 3.75. V pp, D swing on a 50 Ω load. Error-free (BEE < 10-12) transmission at 30 Gbit/s is demonstrated. By using a switched output stage only a small static DC-power is consumed, resulting in the most energy-efficient MZM driver with only 2.2 pJ/bit.
