(2011). A low-pass filter with automatic frequency tuning for a bluetooth receiver. En IEEE International Conference on electronics, Circuits, and Systems (462-465), Atenas, Grecia: IEEE (Institute of Electrical and Electronics Engineers).https://hdl.handle.net/11441/143177A third-order Gm-C Chebyshev low-pass filter with high linearity and automatic frequency programmability has been designed. The filter is intended to be used as a channel-select filter for a zero-IF Bluetooth receiver. The frequency tuning scheme is simpler and has more relaxed specifications than conventional ones. The filter bandwidth is 0.5 MHz and the overall scheme dissipates 1.1 mA from a 1.8-V supply. The third-order intermodulation (IM3) distortion of the filter for a 1Vpp two-tone signal centered at 350 kHz is -67dB.application/pdf4 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Analog CMOS circuitsGm-C filtersLinear transconductorsFrequency tuningDirect-conversion receiversinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1109/ICECS.2010.5724549
