  • Abstract
    In this paper we analyze the 100 nm T-gate structure mechanics, develop the 100 nm MHFMT process with higher structure stability and present a four-stage W-band amplifier with 2×20μm gate width, the total chip size is 3.08× 3.62mm2. The amplifier were measured with a W-band onchip test, a linear gain of 20 dB at 98 GHz and more than 17dB over the bandwidth from 95 to 100 GHz was achieved for a drain voltage Vd of 1.5V and Vg of 0.9V.
