Efficient implementation of 90° phase shifter in FPGA
In this article, we present an efficient way of implementing 90° phase shifter using Hilbert transformer with canonic signed digit (CSD) coefficients in FPGA. It is implemented using 27-tap symmetric finite impulse response (FIR) filter. Representing the filter coefficients by CSD eliminates the need for multipliers and the filter is implemented using shifters and adders/subtractors. The simula...
متن کاملA Wideband 360° Analog Phase Shifter Design
This paper proposes a reflection-type wideband 360 ° analogue phase shifter. The phase shifter employs a branchline coupler circuit to achieve a wideband operation and a varactor-diode circuit to achieve a wide phase-shift range. Analytical formulas are derived to optimize the parameters in the coupler circuit for wideband operation and reduced attenuation ripple, and in the varactor circuit to...
