Fmax of a transistor - Summer @ UCD THz Oscillators - Google
WebTo enable CMOS-compatible GaN HEMTs for the next generation of communication systems (5G and beyond), a low gate resistance is of great importance since it directly affects the RF power gain and fMAX of the transistor. In this article, the impact of various gate-metal stacks on the gate resistance and RF performance of the devices is studied. WebHere we report a systematic investigation of MoS2 transistors with optimized contact and device geometry, to achieve self-aligned devices with performance including an intrinsic gain over 30, an intrinsic cut-off frequency fT up to 42 GHz and a maximum oscillation frequency fMAX up to 50 GHz, exceeding the reported values for MoS2 transistors ... WebOct 30, 2009 · In this letter, f max improvement of a circuit-level radio-frequency (RF) transistor with systematic layout variations is presented in deep-submicrometer CMOS technology. We confirmed that the circuit-level MOS transistor has a tradeoff among the extrinsic capacitive and resistive parasitics ( C gd , C gs , and Rg ) on circular gate metal … ipo leather harness
