The 90degphase bit of high-pass/low-pass phase shifter suffers from large phase error compared to the smaller phase bits. To improve the phase error performance, this work develops a network that provides a differential phase of 90degwith a small phase error (< plusmn2deg) over a large bandwidth. Compared to other work focused on this bit, the new network… CONTINUE READING
