A Study of Nonlinearity Calibration for Six-Port Direct Conversion Receivers
Abstract-A six-port receiver can restore the original modulated signal by calculating the detected envelopes and system parameters of the six-port circuit. The system parameters have been determined at each frequency in advance. The six-port receiver has an advantage in the point that the user can select the frequency arbitrarily, but there is a problem of nonlinear distortion in the detector b...
متن کاملglobal results on some nonlinear partial differential equations for direct and inverse problems
در این رساله به بررسی رفتار جواب های رده ای از معادلات دیفرانسیل با مشتقات جزیی در دامنه های کراندار می پردازیم . این معادلات به فرم نیم-خطی و غیر خطی برای مسایل مستقیم و معکوس مورد مطالعه قرار می گیرند . به ویژه، تاثیر شرایط مختلف فیزیکی را در مساله، نظیر وجود موانع و منابع، پراکندگی و چسبندگی در معادلات موج و گرما بررسی می کنیم و به دنبال شرایطی می گردیم که متضمن وجود سراسری یا عدم وجود سراسر...
An adaptive offset cancellation mixer for direct conversion receivers in 2.4 GHz CMOS
In this paper we present a new circuit design for a 2.4GHz CMOS direct conversion mixer incorporating adaptive offset cancellation. The basic circuit structure is that of a Gilbert cell mixer. Offsets are cancelled by dynamically varying the bias on the loads, which are designed to provide constant impedance independent of the load cancellation current. The bias control is regulated via an adap...
متن کاملDesign Considerations for Direct-Conversion Receivers
This paper describes the issues and tradeoffs in the design and monolithic implementation of direct-conversion receivers and proposes circuit techniques that can alleviate the drawbacks of this architecture. Following a brief study of heterodyne and image-reject topologies, the direct-conversion architecture is introduced and effects such as dc offset, I=Q mismatch, even-order distortion, flick...
متن کاملCompensation of DC-Offsets and RF-Self-Mixing Products in Six-Port-Based Analog Direct Receivers
The cancellation of DC-offsets and 2-order-type RF-self-mixing products (RFS2) is presented for six-port-based, analog direct receiver front-ends. It is shown that the signal dependent RFS2 comprising a dynamic DC-offset as well as the front-end dependent static DC-offset are generated systematically and not only by spurious effects unlike conventional, mixer-based front-ends. Due to this fact,...
