“…Inductive coupling is an effective way to reduce the area of the inductors [11]. In a distributed mixer, an area reduction technique using multi-port inductors has been reported [12]. Although this report demonstrates a small core area of 0.52 mm 2 , the multi-port inductors need to iterate electromagnetic analysis for design optimization.…”

This paper presents an area-efficient differential distributed amplifier using differential coupled inductors. The artificial transmission lines of the proposed distributed amplifier are modeled as differential transmission lines, and thus, it can be easily designed compared with other area reduction techniques. The dimensions of the coupled inductors have been optimized using a gradient descent algorithm with a scalable model of the coupled inductors. The proposed amplifier was designed using 1P5M 180 nm standard CMOS technology. Post-layout simulation results demonstrated a gain of 6.9 dB and a bandwidth of 20.2 GHz with 4.9 ps Nyquist group delay variation. A core area of the proposed amplifier was 0.28 , which was the smallest value compared with previous works using similar processes.

“…Compared to the conventional inductors, the symmetric multi-port Inductor utilizes a lesser area and can provide better inductance density and higher Q values at higher frequencies. In addition to these qualities, this Inductor offers the flexibility to maximize performance in any desired frequency band [6].…”

Portable wireless devices with a high-frequency range should also function with low voltage, providing low power dissipation and noise. Design engineers cannot successfully meet the above design objectives without using RF inductors. Since integrated inductors are an essential part of RF circuits, these devices are highlighted because of their enormous size in the circuit layout and unsettling radiations. As a result, there is a solid motivation to design, optimize, and model inductors made on Si substrates. This article presents the design of a multi-path multi-port 8-shaped inductor with dimensions of 150×150 µm, simulated using Cadence EMX simulator to analyze its Q-factor and inductance. The analysis provided that the simulated inductance has the highest value of 12.2nH, which is the maximum value across all the conclusions of this research. Another significant discovery was that this Inductor is suitable for up to 45GHz. To achieve an improved frequency of operation for the multi-path, multi-port 8-shaped Inductor, an analysis of the Inductor's topology is conducted, focusing on enhancing the loop widths of metal layers and optimizing spacing between the metal tracks.
