In this letter, we present a systematic approach to design compact dual-mode monopole-like patch antenna using characteristic mode analysis (CMA). The modal of slotted circular structure incorporating new shorting pin loading technique is presented. To achieve with the wideband operation, it demonstrated that first two significant modes patterns are most suitable ones for excitation. Based on c...

A broad-band power divider is presented in CMOS technology. The devices are realized by postprocessing chips that are fabricated in a standard 1.2m CMOS process. Developed postprocessing includes wire bonding for ground equalization, deposition of a stress-compensation layer, and selective etching of the silicon substrate. By employing coupled coplanar transmission lines, the area of dividers i...

In this paper, a dual-band power divider is presented based on the propagation of higher-order modes spoof surface plasmon polaritons (SSPPs). A hollow rectangular groove introduced as unit cell, and its dispersion characteristics for higher fundamental mode are examined.

Absbacl-An automatic Inductive Voltage Divider ( I M ) characterization method that can measure linearity by comparing WD’s with differeut structures is suggested. Structural models are employed to decompose an error vector into components that represent each divider. Initial tests at 400 Hz show that it is possible to assign independent errors due to the binary and decade structures with a 27 ...

A new multiplier-divider circuit using a single Current Differencing Buffered Amplifier (CDBA) and only six MOSFETs has been presented. The proposed circuit has the advantage of simultaneously realizing a multiplier and divider without changing the circuit topology. The basic functions of the proposed circuit have been verified through PSPICE simulations using a CMOS CDBA and NMOS transistors w...

A high-frequency divide-by-256–271 programmable divider is presented with the improved timing of the multi-modulus divider structure and the high-speed embedded flip-flops. The D flip-flop and logic flip-flop are proposed by using a fast pipeline technique, which contains single-phase, edge-triggered, ratioed, and high-speed technologies. The circuits achieve high-speed by reducing the capaciti...

Many implementations of division are based on the Newton-Raphson method, as it quickly converges to a solution and can often utilize a multiplier that is already on chip. Applying time shared triple modular redundancy (TSTMR) to such a divider allows the use of a smaller multiplier and requires triplicating the divider circuit. The smaller multiplier completes larger multiplications in several ...

A method used to obtain frequencies in precise ratios of 2/3 and 1/3 of the pump is described as a possible way to extend the usable range of octave-spanning optical frequency combs for frequency metrology applications. The divider is based on a selfphase locked optical parametric oscillation in a doubly resonant semi-monolithic optical cavity containing a dual-grating periodically poled lithiu...
