Design and Analysis of Receiver Front-End of CMOS Cascode Common Source Stage with Inductive Degeneration Low Noise Amplifier on 65 nm Technology Process

In Very Large Scale Integrated (VLSI) and Digital Signal Processing (DSP) applications, a Conventional Combinational Multiplier uses a lot of hardware and propagation delay, and that is one of the main issues. The delay is determined by the ripple carries between the adders. Most techniques used in the combinational multiplier depend on the paper-and-pencil shift-and-add (PPSA) algorithm, which uses ripple carry adder architecture. This paper proposes an architecture called Cell-based Carry-Save Combinational Multiplier (CCCM) that focuses on the propagation delay and area. Each row represents a carry-save adder. The carry outputs are passed to the next row. For validating the proposed architecture, 16x16 multiplication is performed and the overall improvement in the delay is 73.32 % while there is a 3.31 % reduction in the area.

This manuscript presents the 45nm CMOS Low Noise Amplifier (LNA) designed for cryogenic use in spaces. A revised approach has been adopted to classical LNA architecture. External discreet components were added to the LNA in such a way that the LNA S11 and S22 were under –10dB from 70K to 290K at 2.44GHz designated for spatial communications. The LNAs IIP3 performance was analyzed, in particular at cryogenic temperatures, and linearity improvements were demonstrated by using the proposed approach. Although the LNA was not specifically hardened by radiation, no degradation was observed in its performance. Results analysis present that LNA achieves input and output impedance matching’s of -24.024 and -23.131dB, NFs of 0.9dB, power gain of 26.7dB, P-1dB of -10.63dBm, IIP3 of -10.6dBm at 2.44GHz, respectively.
