A tunable low-pass Gm-C filter with 1 GHz cutoff frequency is presented. The core of this filter is a high frequency low voltage operational transconductance amplifier (OTA) in which CMOS inverters are used. For enhancing the linearity of the filter, a novel common mode feedforward circuit is merged...
