Abstract

In modern low-cost , low-power CMOS fully integrated wireless communication system integrated on-chip transformer has begun to be widely used . Chip integrated transformers in the low pressure circuit can be provided without a loss of voltage swing interstage coupling ; feedback network of low noise can be introduced in the RF circuit ; the more important components of the quadrature voltage-controlled oscillator (QVCO) . With Moore's Law (Moor's Law) remain in effect and continue to reduce the operating voltage of the system - on - chip (SoC) , the role of the integrated transformer increasingly significant . Must first create accurate models for on-chip integrated transformer design applications . The main work of this paper is to establish integrated on-chip transformer model , has a high practical value . In recent years , has been integrated on - chip transformer research literature , often distributed parameter model, which is complex and not intuitive . To address this issue , the main work of this paper : 1 ) to establish contains electromagnetic phenomena as well as an important influence on the transformer performance of parasitic parameters the amount of physical model ; 2 ) numerical fitting of parasitics , to establish a more intuitive \lumped parameter model ; 3 ) does not change the process conditions for optimization of the transformer provides theoretical guidance ; 4) providing intuitive , reliable solution for integrated on - chip transformer design applications . TSMC 0.25μm CMOS 1P5M Mixed Signal process flow sheet testing transformer model presented in this paper . Experimental results show that the accuracy of the model , to verify the effectiveness of the optimization method . On the basis of the establishment of the transformer model designed applications small wireless LAN in the low voltage 2.4GHz RF low- noise amplifier , and tapeout verification , to prove the accuracy of the proposed model . The circuit to achieve impedance and noise matching the same time , shows the on-chip integrated transformer its performance improved significantly in the low-voltage RF front-end circuit .
