摘要
在传统共源-共栅-共漏(CS-CG-CD)有源电感的基础上,提出一种改进型有源电感。在负跨导器的CG晶体管与正跨导器的CD晶体管之间引入带有并联电阻的第一反馈回路和具有小尺寸晶体管的第二反馈回路;另外,在负跨导器的CS晶体管与正跨导器的CD晶体管之间引入调控支路;最终,通过不同模块的相互配合及其他三个外部调控端电压的联合调节,实现了对电感性能的两种重构:1)在同一频率下取得高的Q峰值且Q峰值相对L值可大范围独立调节;2)在不同频率下取得高的Q峰值且Q峰值保持基本不变。验证结果表明,在频率5.81 GHz下,Q峰值可从1132调谐到15491,调谐范围高达1268.5%,而电感值在7.65~7.67 nH之间变化,变化率仅为0.26%;在频率5.72 GHz、7.12 GHz和7.93 GHz下,分别取得了1274、1317和1310的高Q峰值,Q峰值变化率仅为3.38%,同时分别取得了大的电感值7.62 nH、8.08 nH和8.81 nH;有源电感的直流功耗约为38.61 mW。
Based on traditional common source-common gate-common drain(CS-CG-CD)active inductors(AI),an improved Al is proposed.Firstly,both the first feedback loop with parallel resistance and the second feedback loop with small size transistor were introduced between CG transistor of the negative transconductor and CD transistor of the positive transconductor.Secondly,the tuning branch circuit was introduced between CS transistor of the negative transconductor and CD transistor of the positive transconductor.Furthermore,the cooperation among above different modules and the joint adjustment of their external tuning terminal voltages realized two reconfigurable performances as follows:1)high Q peak values could be achieved and tuned independently relative to the inductance values in a large range at the same frequency;2)high Q peak values could be obtained and kept almost unchanged at different frequencies.The verification results show that at the frequency of 5.81 GHz,the Q peak value can be adjusted from 1132 to 15491 with the tuning percentage of 1268.5%.Meanwhile,the inductance values change from 7.65 nH to 7.67 nH with the variation of only 0.26%.Under the frequencies of 5.72 GHz,7.12 GHz and 7.93 GHz,the Q peak values can be high up to 1274,1317 and 1310 respectively,and the variation percentage is only 3.38%.Meanwhile,the large inductance values of 7.62 nH,8.08 nH and 8.81 nH can be obtained respectively.It consumes about 38.61 mW.
