A S-band monolithic integrated switched filter bank has been designed to realize tunable working center frequency, and a tuning range of 12.9% from 2.7 to 3.05GHz was achieved with interval of 50MHz. The switched filter bank is designed using 8 eighth-order step impedance resonators (SIR) band-pass filters arranged in parallel rows. Microelectromechanical Systems (MEMS) switched circuit is inte...

A Novel circuit configuration for realizing multi-output four-terminal floating nullor in biopolar monolithic integrated circuit form is described. The circuit is simple and based on the use of an improved translinear cell type circuit, which provide wide bandwidth and dynamic range. The characteristics of this circuit are confirmed by HSPICE simulation results. The performance of the FTFN-base...

Monolithic integrated lumped planar transformers were introduced more than ten years ago. We present a comprehensive review of the electrical characteristics which results in an accurate lumped low-order equivalent model. Amplifiers, mixers and Meissner-type voltage controlled oscillators using monolithic transformers have been published a few years ago. For the first time, integrated transform...

Analysis and design techniques for designing a lumped-element 3-dB quadrature coupler with wide-band flat coupling are proposed for microwave integrated-circuit/monolithic-microwave integrated-circuit applications. The proposed design technique can produce a coupler with flat coupling over 50% fractional bandwidth, which is wider than the conventional lumped-element design methods. A prototype ...

In this paper, we look at different possibilities and advantages of our early proposed hybrid planar and nonradiative dielectric (NRD) guide technology in the design of various millimeter-wave circuits. First of all, an overview of the NRD guide technology progress is presented. It indicates that the hybrid planar/NRD-guide (HP/NRDG) technology provides a straightforward assembly of MMIC circui...

This paper presents an overview of the terahertz (THz) resonant tunneling diode (RTD) technology that will be used as one of the approaches towards wireless data centres as envisioned on the EU H2020 TERAPOD project. We show an example 480 m × 680 m THz source chip at 300 GHz employing a 4 μm × 4 μm RTD device with 0.15 mW output power. We also show a basic laboratory wireless setup with this...

A methodology for guiding process-driven manufacturing organizations in instituting process control on a facility-wide basis is proposed. The methodology begins with a definition of the customer’s expectations and of the manufacturing process used to meet these expectations. The output, of a given process or subprocess must reach four progressive levels of control. When the output can be reliab...

In this work, a 3D capacitive coupling structure employing periodic pattern was used for application to miniaturized on-chip passive components on MMIC (Monolithic Microwave Integrated Circuit). Unlike conventional periodic structure, the characteristic impedance of the 3D capacitive coupling structure was hardly dependent on frequency. Using the 3D capacitive coupling structure, RF passive com...
