“…From (1), continuous magnitude and phase control can be achieved by properly adjusting the gains of the two VGAs and the phase of the 0/180° phase shifter sections, covering all four quadrants of the complex plane. For example, if one wishes to obtain the coordinate (1,1) in the normalized complex plane, one would set the normalized gain of A and B to be both 1, and θ a and θ b to be 0°; for the coordinate Phase shifters are one of the key components used in phase array systems such as electronic beam steering elements and n other systems such as modulators [1]. Active phase shifters using the vector sum method can provide continuous phase shift or multi-bit operation with low loss [2]- [8].…”

The design and measurement results of a continuous amplitude/phase control CMOS MMIC are presented in this paper. This circuit uses the vector sum method to achieve continuous phase and amplitude control. The phase shifter demonstrates all continuous phase control and an insertion loss of 17 dB with 30-dB dynamic range from 40 to 75 GHz. The chip size is only 0.7 mm × 0.6 mm. To the best of the authors' knowledge, this circuit is the first demonstration of millimeter-wave phase shifters MMIC using the vector sum method, with the smallest chip size for all MMIC phase shifters and 360° phase-control circuits in frequencies above 5 GHz reported to date.Index Terms-CMOS, monolithic microwave integrated circuit (MMIC), phase shifter, vector sum method.

An innovative vector-sum phase shifter with a full 360 variable phase-shift range in 0.18-m CMOS technology is proposed and experimentally demonstrated in this paper. It employs an I/Q network with high I/Q accuracy over a wide bandwidth to generate two quadrature basis vector differential signals. The fabricated chip operates in the 2.3-4.8 GHz range. The root-mean-square gain error and phase error are less than 1.1 dB and 1.4 over the measured frequency span, respectively. The total current consumption is 10.6 mA (phase shifter core: 2.6 mA) from a 1.8 V supply voltage and overall chip size is 0.87 0.75 mm . To the best of the authors' knowledge, this circuit is the first demonstration of microwave CMOS phase shifter with very low phase error over a wide bandwidth employing the vector sum method for all monolithic microwave integrated circuit phase shifters with 360 phase-control range to date.Index Terms-Active phase-shifter, CMOS analog integrated circuit, differential amplifier, I/Q network, phased array.

Complex and dynamic control of radiated fields are advantageous for flexible radio systems, which naturally move, roll, bend, twist, deform, and vibrate. Practical challenges hinder the proliferation of these antenna arrays. This work shows how using radio-frequency microchips reduces system component count, decreases mass to ~0.1 g cm−2, and increases functionality and mechanical flexibility. We develop a general platform for large scale flexible arrays and demonstrate two different 256-elements, 30 × 30 cm2 flexible arrays. By varying supply distribution methods and radiators we show how performance can be optimized for maximum power delivery or physical flexibility. The demonstrated systems conform to curved surfaces with radii of curvatures as low as 23 cm and wirelessly deliver ~ 80 mW of DC power to a 6.7 cm × 11 cm-receiver over one meter away. This paves the way towards the integration of smart arrays in flexible wearables and deployable lightweight airborne systems.
