Design of an On-Chip Balun With a Minimum Amplitude Imbalance Using a Symmetric Stack Layout

IEEE Transactions on Microwave Theory and Techniques, 2010
This study develops a compact balun layout to minimize amplitude imbalance. Three baluns with different metal layers are fabricated using 0.13-?m CMOS technology and their imbalance performance evaluated. Measurement made using eight metal layers in coil windings at a particular layout reveal that the proposed device exhibits minimal amplitude and ...

An I/Q Amplitude-phase Imbalance Correction Algorithm in IF Receiver

2021 IEEE 4th International Conference on Electronic Information and Communication Technology (ICEICT), 2021
In this paper, a correction algorithm for I/Q amplitude and phase imbalance in IF receiver is proposed, which can solve the problem of image frequency caused by I/Q amplitude and phase imbalance. The test results show that in 25MHz bandwidth, 10MHz bandwidth and 1MHz bandwidth, the IRR before and after correction has been significantly improved.

Impact of I/Q Amplitude Imbalance on Coherent $\Phi $ -OTDR

Journal of Lightwave Technology, 2018
In this paper, the quadrature amplitude imbalance which may consist in I/Q demodulated phase-sensitive optical time-domain reflectometry ( $\Phi $ -OTDR) is analyzed, which may happen in both ac and dc components of received signals. Based on the analysis of imperfect coherent detection module, the impacts of each imbalance factor on the demodulated ...
