A 2.4-GHz highly linear derivative superposition Gilbert cell mixer

UWB, high gain and highly linear Gilbert-Cell mixer in K-band

This paper presents a K-band Gilbert mixer in a 0.18μm CMOS technology by means of a π-Network and Post Distortion Cancellation (PDC) technique to achieve high gain, high linearity, and moderate noise figure. We use the parasitic capacitances that appear at nodes between RF and LO stage for implementing π-Network. Circuit analysis and MATLAB simulation show that the above technique is useful fo...

Harmonic Rejection in 2.4 GHz Gilbert Cell Mixer for Terrestrial Microwave Communication systems

Mixer is one of the significant components of the radio frequency transceiver that translate baseband signal into RF and vice versa. In this paper, 2.4 GHz double balanced Gilbert Cell Mixer topology was simulated to study its important properties such as Conversion Gain, Linearity, Noise Figure and Port Isolation. Further, a band pass filter is added in to the design at IF port so as to reject...

A 2 GHz Highly Linear Downconversion Mixer in 0.18- m CMOS

This paper describes a 2 GHz CMOS active balanced downconversion I/Q mixer in a TSMC0.18m process for a WCDMA receiver. The mixer achieves a conversion gain of 16 dB and a double side band (DSB) NF of 13.8 dB. The mixer's IIP3 is 12.12 dBm. It consumes approximately 5 mA of current from a 1.8-V power supply. The 12.12 dBm IIP3 fulfils the UMTS requirements for a mixer design.
