Abstract

本发明公开了一种超低压实现带通滤波器的双二阶单元,属于滤波器技术领域。所述双二阶单元包括:第一跨导模块,用于接收输入电压信号,并将输入电压信号转换为电流信号;第一差分电容,与第一跨导模块相连,形成第一积分单元,用于确定双二阶单元传输函数的复数共轭极点;第二跨导模块,用于接收输出电压信号,并将输出电压信号转换为电流信号;第二差分电容,与第一跨导模块和第二跨导模块相连,形成第二积分单元,用于确定双二阶单元传输函数的复数共轭极点;电流源模块,与第一跨导模块相连,用于提供双二阶单元的支路电流。本发明提供的双二阶单元,结构简单,容易实现,有效地降低了带通滤波器电路结构的复杂度和功耗,实现了超低电源电压。
