This paper presents a Gray-code addressing time division multiplexing (TDM) clocked-analog low-dropout regulator (CLDO) that shares one controller between four output channels with only one compensation capacitor. We apply the Gray-code addressing strategy to reduce the crosstalk. We also apply the split-output amplifier structure to share the compensation capacitor for further chip area reduction. In addition, we introduce a lightweight local-generated supply to increase the dynamic range. Implemented in 130 nm CMOS process, this design has a total chip area of 0.056 mm2 , which is 67.5% smaller than the conventional solution with four identical LDOs. Post layout simulation results show that the presented four-channel TDM CLDO can simultaneously track four 1 V<sub>pp</sub> sinusoidal signals at different frequencies with negligible crosstalk. This TDM CLDO is a promising solution for supplying multiple thermo-optic phase shifters (TOPSs) in silicon photonics

In this review materials and technologies of the hybrid approach to integrated photonics (IP) are addressed. IP is nowadays a mature technology and is the most promising candidate to overcome the main limitations that electronics is facing due to the extreme level of integration it has achieved. IP will be based on silicon photonics in order to exploit the CMOS compatibility and the large infrastructures already available for the fabrication of devices. But silicon has severe limits especially concerning the development of active photonics: its low efficiency in photons emission and the limited capability to be used as modulator require finding suitable materials able to fulfill these fundamental tasks. Furthermore there is the need to define standardized processes to render these materials compatible with the CMOS process and to fully exploit their capabilities. This review describes the most promising materials and technological approaches that are either currently implemented or may be used in the coming future to develop next generations of hybrid IP devices.
