This paper presents a complementary current-mode 2 nd order Gm-C filter for 5G and other broadband applications. The filter structure is based on 2 complementary differential pairs in order to achieve both low noise and high frequency performances. A bandwidth of higher than 1 GHz is achieved with a gain of 0dB and an in-band IIP3 of 29dBm, consuming less than 27mW from a 1.8V supply. The filter is fabricated in a 65nm CMOS process with a core circuit area of 0.1mm×0.08mm.

The energy consumption per transmitted bit is becoming a crucial figure of merit for communication channels.In this paper, we study the design trade-offs in photodetectors, utilizing the energy per bit as a benchmark. We propose a generic model for a photodetector that takes optical and electrical properties into account. Using our formalism, we show how the parasitic capacitance of photodetectors can drastically alter the parameter values that lead to the optimal design. Given certain energy-per-bit and bandwidth requirements, is it possible that a photodetector optimized for the energy per bit would be noise limited. We identify different noise sources and model them in the simplest useful approximation in order to calculate this noise limit. Finally, we apply our theory to a practical case study for an integrated plasmonic photodetector, showing that energies per bit below 100 attojoules are feasible despite metallic losses and within noise limitations without the introduction of an optical cavity or voltage amplifying receiver circuits.

Thermal noise performance in recent CMOS technologies

Abstract: This paper reviews the measurement and modeling issues of the channel thermal noise in MOSFETs as a result of the aggressive reduction of the channel length into the sub-l00 nm regimes. It also shows the noise performance of devices in 65 nm CMOS technology.
