Abstract

This paper presents a switched-inductor dual-band injection locked frequency divider (ILFD) fabricated in a 0.35-um CMOS process. The circuit is made of a differential double cross-coupled CMOS LC oscillator with a switched-inductor LC-tank, which consists of a parallel LC tank in parallel with one switched inductor composite. The dual-band function is obtained by switching the MOS switch in the inductor composite. At the supply voltage of 2.4 V, the measured free-running frequencies of the divide-by-two dual band ILFD are from 2.52 GHz to 2.61 GHz for the low-frequency band and from 4.18 GHz to 4.39 GHz for the high-frequency band. At the incident power of 0 dBm. the locking ranges of low-frequency and high-frequency band are respectively from 4.0 GHz to 5.8 GHz and from 7.1 GHz to 9.3 GHz.

一个0.35微米CMOS开关电感双带LC-tank分频器

本文提出了一种开关电感双带注入锁定分频器(ILFD)，该分频器采用0.35 μ m CMOS工艺制造。该电路由差分双交叉耦合CMOS LC振荡器和开关电感LC槽组成，该开关电感LC槽由一个并联的LC槽与一个开关电感并联组成。双频功能是通过开关电感复合中的MOS开关来实现的。在电源电压为2.4 V时，测量到的分二双频ILFD的低频自由工作频率为2.52 GHz ~ 2.61 GHz，高频自由工作频率为4.18 GHz ~ 4.39 GHz。在入射功率为0 dBm时。低频锁定范围为4.0 GHz ~ 5.8 GHz，高频锁定范围为7.1 GHz ~ 9.3 GHz。
