“…Although there are some discrepancies between the measurement and simulation, mainly due to limitations in modeling, the results are still in relatively good agreement. Compared to the state of the arts of 90 phase shifters which is shown in Table I [7], [8]. The proposed phase shifter shows the lowest average insertion loss with an acceptable size.…”

This letter presents a highly integrated 1-bit 90 phase shifter based on high-pass/low-pass structure for 60 GHz beamforming applications using a standard 65 nm CMOS process. In order to overcome the limitation of the conventional low-pass only phase shifter, the combination of high-pass/low-pass network was utilized as a 1-bit phase shifter. By integrating a high pass network into the low-pass network with low loss single-pole single throw (SPST) switches that adapt a resistive body floating technique, the proposed phase shifter achieves average 5 dB IL and less than dB of insertion loss flatness and 1 dB rms amplitude error over the whole band in a small chip area of 0.16 mm including pads.

In this article, we present the design and the measurement of two hybrid couplers for millimeter‐wave applications realized in the BiCMOS9MW 130nm process (ST Microelectronics). The aim is to demonstrate several miniaturization possibilities of a conventional branchline coupler while maintaining a constant 90° phase shift and a low insertion loss over the full 57–66‐GHz band. The first miniaturized coupler is composed of meandered transmission lines; the second is a quasi‐lumped quadrature coupler with discrete capacitors. The performance of these circuits is compared with the most recent on‐chip 60‐GHz couplers. We especially demonstrate the possibility to achieve state‐of‐the‐art performance while using miniaturization techniques. © 2012 Wiley Periodicals, Inc.

“…It is composed mainly of two topologies: 1) reflective-type phase shifter (RTPS) [7]- [10] and 2) switched-type phase shifter (STPS) [11]- [17]. In [8] and [9], compact 60-GHz RTPS designs with good phase responses and low insertion loss were presented. However, the total phase shift ranges were limited to 180°, because the insertion loss variation in different phase states will become too large for a 360°design.…”

This paper presents the design of a compact 60-GHz phase shifter that provides a 5-bit digital phase control and 360°phase range for beam-forming systems. The phase shifter is designed using the proposed cross-coupled bridged T-type topology and switched-varactor reflective-type topology. The topologies are analyzed using a small-signal equivalent circuit model. Furthermore, the design equations are derived and investigated. To validate the theoretical analysis, 60-GHz 5-bit 360°phase shifters are designed in a commercial 65-nm CMOS technology. The fabricated 360°phase shifter features good performance of 32 phase states from 57 to 64 GHz with an rms phase error of 4.4°, a total insertion loss of 14.3 ± 2 dB, an rms gain error of 0.5 dB, P 1 dB of better than 9.5 dBm, and the power consumption of almost zero. To the best of our knowledge, the designed 360°phase shifter with the size of 0.094 mm 2 is the smallest 5-bit passive phase shifter at frequencies around 60 GHz.Index Terms-60 GHz, beam forming, bridged T-type phase shifter, CMOS, digital control, millimeter-wave (mm-wave), phase shifters, phased array, reflective-type phase shifter (RTPS), switched-type phase shifter (STPS), V -band, variable phase shifters.
