A Self-Body-Biasing Network of Vector Sum Phase Shifter for Reduction of Output Capacitance Variation and Supply Current Variation
Autor: Junhan Lim, Gwanghyeon Jeong, Songcheol Hong
Publikováno v: IEEE Access, Vol 12, Pp 114460-114464 (2024)
This paper presents the self-body-biasing effects of a vector-sum phase shifter(VSPS) in 0.13- $\mu $ m CMOS technology. The self-body-biasing network is simply implemented by connecting the drain and body terminals of a vector-sum MOSFET amplifier t

A Ka-Band Variable-Gain Phase Shifter With Multiple Vector Generators
Autor: Gwanghyeon Jeong, Jinseok Park, Songcheol Hong
Publikováno v: IEEE Transactions on Circuits and Systems II: Express Briefs. 68:1798-1802
A Ka-band variable-gain phase shifter (VGPS) using a multi-vector summation method is proposed, which represents both phase and amplitude by summing the I and Q signals of multiple vectors. The VGPS has an orthogonal phase and gain control function w

28-GHz CMOS Power Amplifier Linearized With Resistive Drain-Body Connection
Autor: Gwangsik Cho, Songcheol Hong, Gwanghyeon Jeong
Publikováno v: IEEE Microwave and Wireless Components Letters. 30:876-879
A 28-GHz two-stage differential cascode power amplifier (PA) linearized with a simple common-source (CS) body network, in which the body of the CS amplifier at the power stage is connected to the drain through a large resistance. The body network is

An Integrated Dual-Mode CMOS Power Amplifier With Linearizing Body Network
Autor: Seunghoon Kang, Songcheol Hong, Taehwan Joo, Gwanghyeon Jeong
Publikováno v: IEEE Transactions on Circuits and Systems II: Express Briefs. 64:1037-1041
A dual-mode radio frequency CMOS power amplifier (PA) for Internet of Things application is presented, which is integrated with the other circuits in a 55-nm bulk CMOS process. The low-power mode is achieved by reducing the number of turn-on power tr

A cascode linear power amplifier with reduced capacitance variation of common gate transistors
Autor: Songcheol Hong, Taehwan Joo, Gwanghyeon Jeong, Seunghoon Kang
Publikováno v: Microwave and Optical Technology Letters. 59:125-128
A common-gate (CG) transistor in a cascode power amplifier has a large input capacitance variation in the saturation region with respect to the source voltage. This causes large nonlinearity in a CMOS PA that utilizes a cascode configuration. Here, w
