“…The Gilbert cell adopted in this paper can obtain great isolations between the LO-IF ports and LO-RF ports, which can effectively suppress the LO signal leakage. According to the known theory, the parasitic capacitance of the switch to the common source node, the approximate degree of the idealized switching MOS transistors the matching degree of the switch to the CMOS transistor all have an important influence on the LO signal leakage of the zero-IF mixer [6]. Therefore, by optimizing the amplitude of the LO signal, the size and layout design of switch transistors can suppress LO signal leakage so that reduce the DC offset.…”

“…At an earlier time, researchers achieve higher IIP2 performance through some simple circuit methods, such as using transimpedance (TIA) stage [6], overcoming LO self-mixing problem [7], using programmable nonlinear current injection [8] and so on. However, the IIP2 performances of these methods are not as sufficient as with the development of the requirements.…”

This paper presents a high performance I/Q zero intermediate frequency (IF) mixer with a second-order input intermodulation point (IIP2) calibration technique in 45nm SOI CMOS process. A behavioral model of the mixer is established to analyze the sources of the second-order intermodulation distortion (IMD2). Based on the analysis, a high accuracy load resistance modulation array is applied to achieve excellent IIP2 performance. The frequency of the local oscillator (LO) signal is 3.5GHz, while the RF input signal frequency range is 3.4GHz∼3.6GHz. Simulation results show that the proposed zero-IF mixer achieves a conversion gain of more than 9.2dB with the input 1dB compression point of -11.28dBm. Noise figure is about 16.9dB at 10kHz and lower than 11.6dB at the frequency above 1MHz. The IIP2 of the circuit is larger than 66dBm after the calibration, which increases more than 40dBm.

Presence of noise significantly degrades the contents being transmitted over GSM channel. With the evolution of next generation of communication system, the challenges in noise cancellation in voice along with data transmission are not being addressed effectively by existing filters. Therefore, the proposed system offers a mechanism where emphasis is laid on identification of superior and inferior forms of GSM transient signal followed by cancellation of its noise level. Designed using analytical methodology, the proposed system harness the potential of probability theory to perform a modeling that associates allocated power of the transmitting device with the level of noise. The outcome of the study is found to offer a comprehensive identification of different forms of noise and can precisely determine the level of superior and inferior quality of signal. The outcome significantly assists in designing an accurate filter for noise cancellation in GSM signal.
