Abstract This paper presents a novel GmC complex filter approach with high image rejection for standard wireless receiver applications. The filter is implemented with a new architecture in 130nm CMOS process. Since by conventional approach, to get more IRR, the order of the filter has to be increased, where as by using novel approach 55 dB IRR is achieved with a just a second order Complex band pass filter and a first order complex notch filter. By using this novel architecture the desired IRR band can be achieved with less number of stages with improved complex band pass response. The quality factor is improved and power consumption is also reduced when compared with the conventional approach design. In this paper the novel architecture is designed for blue tooth low energy receiver applications with center frequency of 4MHz and bandwdth of 2MHz with power consumption of 54 W. To consume low power a novel design of Operational Trans conductance amplifier with bulk driven is proposed with a 0.5 V supply in this paper.
