摘要
Design of super compact on-chip inductors with deep-shrunk dimension of 22mumx23mum, as opposed to several hundreds gm by several hundreds gm, is reported. Implemented in a 6-metal all-copper 0.18mum CMOS process, a flat inductor value of 10nH up to 4GRz, satisfactory to many typical RFIC applications, is achieved. The aggressive shrinkage reduces parasitic capacitance substantially and makes it realistic and cost-effective to realize sing-chip RFICs in very deep sub-micron technologies. A new inductor model is proposed for accuracy. A 2/4GRz LNA circuit with on-chip matching using the compact inductor is demonstrated.
