Output voltage swing in a CMOS differential amplifier with active load

This paper investigates the output voltage swing (Vos) of a CMOS differential amplifier with active load, implemented in ۹۰ nm CMOS technology. The analysis explores the impact of temperature and process corners on Vos, considering three distinct operating scenarios:۱.Temperature = ۲۷°C, Process Corner = TT (Typical)۲.Temperature = -۴۰°C, Process = FF (Fast-Fast)۳.Temperature = ۸۵°C, Process Corner = SS (Slow-Slow)The analysis employs SPICE simulations to assess how these factors influence the amplifier's ability to produce a large linear output voltage swing. In this article, we used the HSPICE simulation tool. The differential amplifier is one of the most important circuit inventions and dates back to the time of electronic lamps. Differential operation is one of the main options in analog and mixed-signal circuits due to its many advantages. This circuit will have ۶ MOSFETs and as a result, ۱۲ MOSFET channel lengths and thicknesses.
