These circuits encompass grounded OTA capacitors only, so that filter characteristic can be tuned and set-up by adjusting the trans-conductance versus capacitance ratio and can be integrate to realize continuous-time current-mode filter. 由于电路仅用接地的OTA及电容实现,滤波器的特性决定于跨导电容比,因而这些电路适于实现全集成连续时间电流滤波器。
The high frequency matching network mainly used lumped element lowpass network, including the series capacitance, series inductance and shunt grounded capacitance. 高频匹配网络主要采取集中参数低通形式,串联部分电感、电容参加匹配,并联部分对地电容参加匹配。
