A 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...
متن کاملA Wideband Current-mode, Low-Voltage, Low-Power CMOS Frequncy- insensitive Quadrature Phase Shifter
A CMOS frequency-insensitive quadrature phase shifter is presented. Due to operation in current-mode, the proposed circuit provides a wide frequency response, a low supply voltage, low power consumption and electronic controllability. Thus, it is very suitable for use in portable and battery-powered equipments. The feature of the proposed circuit is that it can provide the quadrature signals wi...
متن کاملWideband 180◦ Phase Shifter Using Microstrip-cpw-microstrip Transition
Abstract—A microstrip 180◦ phase shifter obtained by a novel design of Microstrip-to-Coplanar Waveguide (CPW)-to-Microstrip transition is presented. The proposed phase shifter is obtained without changing the layer of the second microstrip line. Via holes are used to transfer the current from the top to the bottom substrate layer and vice versa. The presented phase shifter is operating in a wid...
متن کاملA Fully Balanced Pseudo-Differential OTA With Common-Mode Feedforward and Inherent Common-Mode Feedback Detector
A pseudo-differential fully balanced fully symmetric CMOS operational transconductance amplifier (OTA) architecture with inherent common-mode detection is proposed. Through judicious arrangement, the common-mode feedback circuit can be economically implemented. The OTA achieves a third harmonic distortion of 43 dB for 900 mVpp at 30 MHz. The OTA, fabricated in 0.5m CMOS process, is used to desi...
متن کاملCompact Differential Bandpass Filter with Improved In-band Common-mode Suppression with Loaded T-shaped Resonators
Compact symmetrical four-ports differential bandpass filters with good common-mode suppressions are proposed in this work. The presented filters are designed based on half-wavelength coupled resonators with compact size, good filtering responses for differentialmode, and wide common-mode suppression range. To further improve the common-mode performances within the differential-mode passband, T-...
