With the current advancements in quantum computing moving more circuitry into the cryogenic chamber there is a need for high-speed connectivity between the cryogenic and room temperature environment. Studies conducted to date have achieved high-speed links of multiple Gb/s utilizing a single CMOS chip at room temperature, yet a Cryo-CMOS wireline transmitter addresses a new topic in high-speed cryogenic electronic design necessary for the functioning and scale-up of quantum computers. This thesis entails the design of A DAC-based Cryo-CMOS 51.2 Gb/s PAM4 Wireline Transmitter. Overall, the proposed design is meant to demonstrate a high-speed signal generated by a Cyro-CMOS chip can be send through a cable from a cryogenic environment and received at room temperature. Requirements have been set up based on the measurement of the cable channel and simulation results showed these could be met with the designed circuitry. The system consists of a low-speed 16-to-1 serializing structure, a high-speed 4-to-1 Multiplexer, and a 6-bit (4b binary, 2b unary) CML DAC. The design is finished and taped out in 40-nm technology, however the chip is still in fabrication, so the results are based on simulation data only, in future research measurements will verify the working of the chip.

The development of swarm robotics strives for resilience, a key factor in this is energy supply. Without energy a robot swarm cannot operate, so a self sustaining power management system is of great importance. In this thesis, the design of the power management system control hardware and firmware for the new DeciZebro is discussed. The power flow between the battery and peripherals of the robot will be controlled with safety as a top priority. The firmware of the power system reflects the thinking and being of a real animal in code. When the power system wants to recharge it will tell the brain of the robot to get back to a charging station. In case of an error, a pain signal in the form of an interrupt is send through the nerves of the robot. The firmware and hardware design is done, and several parts of the system have been tested and verified. The prototype PCB is completed, however testing has not yet taken place at the current time.
