A 0.18μm CMOS 9mW Current−Mode FLF Linear Phase Filter with Gain Boost

چکیده
−The design and implementation of a CMOS continuous-time follow−the−leader−feedback (FLF) filter is described. The filter is implemented using a fully−differential linear, low voltage and low power consumption operational transconductance amplifier (OTA) based on a source degeneration topology. PSpice simulations using a standard TSMC 0.18μm CMOS process with 2V power supply have shown that the cut-off frequency of the filter ranges from 55MHz to 160MHz and dynamic range is about 45dB. The group delay is less than 5% over the whole tuning range; the power consumption is only 9mW.
