200nm gate-length GaAs-based InAlAs/InGaAs MHEMTs are fabricated by MBE epitaxial material and EBL (electron beam lithography) technology. Ti/Pt/Au is evaporated to form gate metals. A T-shaped gate is produced usin...
An improved charge-averaging charge pump and the corresponding circuit implementation are presented. The charge-averaging charge pump proposed by Koo is analyzed and a new scheme is proposed. This new scheme decreases...
