Abstract

本发明涉及一种基于负反馈的二阶带通滤波器,属于模拟滤波器设计领域。采用PMOS管或NMOS管实现,该二阶带通滤波器包括第一NMOS管M3l、第二NMOS管M3r、第三NMOS管M2l、第四NMOS管M2r、第五NMOS管M1l、第六NMOS管M1r、第一电容C1l、第二电容C2l、第三电容C2r、第四电容C1r、第一电流源Ib1和第二电流源Ib2;本发明基于负反馈技术,不需要共模反馈电路,有效地降低功耗;仅仅使用了八个晶体管实现一个双二阶单元,要实现四阶带通滤波器仅需要十六个晶体管,结构对称简单,易于设计,有效地降低了带通滤波器电路结构的复杂度;还可以通过控制第一PMOS管和第二PMOS管与第五PMOS管和第六PMOS管的跨导比例来调整通带增益。
