Spectral Purity Enhancement via Polyphase Multipath Circuits
نویسندگان
چکیده
The central question of this paper is: can we enhance the spectral purity of nonlinear circuits by using polyphase multipath circuits? The basic idea behind polyphase multipath circuits is to split the nonlinear circuits into two or more paths and exploit phase differences between these paths to cancel undesired distortion products. It turns out that it is very well possible to use polyphase multipath circuits to cancel distortion products produced by a nonlinear circuit. Unfortunately, there are also some spectral components that cannot be canceled with the polyphase multipath circuits. Keywords—Distortion, Harmonics, Polyphase, Multipath, Cancellation

Unified Frequency-Domain Analysis of Switched-Series- RC Passive Mixers and Samplers
A wide variety of voltage mixers and samplers are implemented with similar circuits employing switches, resistors, and capacitors. Restrictions on duty cycle, bandwidth, or output frequency are commonly used to obtain an analytical expression for the response of these circuits. This paper derives unified expressions without these restrictions. To this end, the circuits are decomposed into a pol...

In this chapter we discuss flexible cognitive radio circuits for dynamic access of unused spectrum. Ideally, such circuits can work at an arbitrary radio frequency (RF). We review techniques to realize radios without resorting to frequency selective dedicated filters [24], in particular a recently proposed polyphase multipath technique canceling harmonics and sidebands [11,12]. Using this techn...

Direct sequence code division multiple access (DS-CDMA) communication systems using random polyphase sequences with coherent reception in multipath fading channels are considered. By examining the asymptotic characteristics of the multiple access interference and multipath interference, we show that the DS-CDMA system performance with random mp-phase sequences of mp 3 is better than that with r...
