Abstract:
A 302.5-GHz high-gain CMOS THz amplifier is proposed in this work. An electromagnetic (EM) modeling approach, verified by transistor measurements, is employed to optimize transistor layout, effectively reducing gate resistance and drain-to-gate capacitance. This significantly enhances the transistor’s maximum oscillation frequency $f_{mathrm {max }}$ from 239.7 to 367.5 GHz. Furthermore, a $…
