A scalable and highly accurate RF symmetrical inductor model (with model error of less than 5%) has been developed from more than 100 test structures, enabling device performance versus layout size trade-offs and optimization up to 10 GHz. Large conductor width designs are found to yield good performance for inductors with small inductance values. However, as inductance or frequency increases, ...

Synchronous buck converters generate broadband noise typically in 50 – 300 MHz range due to the parasitic LC resonance in the switching loop which consists of input decoupling capacitors, high-side MOSFET and low-side MOSFET. Typically, this parasitic resonance is attenuated using an R-C snubber placed parallel to the low-side MOSFET. However, selection of the R and C value of the snubber is no...

In this paper, a CMOS radio frequency (RF) multi-band band-pass amplifier using a high-Q active inductor load with a binary code band selector suitable for multi-standards wireless applications is proposed. By employing the improved high-Q active inductor including two bits binary controlled code, the RF multi-band amplifier operating at four different frequency bands is realized. The proposed ...

Introduction Recently the concept of traveling wave excitation was demonstrated for high field MRI (1). In these experiments RF excitation and reception was done by using a patch antenna, suited for this task. The disadvantage of this antenna, however, is its size. A proper patch antenna for 7 T MRI is almost as large as the diameter of the bore. This limits the location of the antenna to the e...

In airborne AC power system, input current may distort at the vicinity of input voltage zero crossing in Power Factor Correction (PFC) converter. This paper is analyzed the essential causes of the zero-crossing distortion and points out that the major causes are the value of inductor and the phase displacement between input current and input voltage. By adopting parallel interleaving technique,...

In this work, we present new topologies for realizing one lossless grounded inductor and two floating, one lossless and one lossy, inductors employing a single differential difference current conveyor (DDCC) and a minimum number of passive components, two resistors, and one grounded capacitor.

In this broadband amplifier, the compact high-Q active inductor is connected to the common-gate configuration to improve the performance of the high power gain, wide bandwidth, low power consumption and simple matching characteristics. Not using any passive inductor components is to be reduced the are...

A novel high step-up DC-DC converter with coupled-inductor and switched-capacitor techniques is proposed in this paper. The capacitors are charged in parallel and are discharged in series by the coupled inductor, stacking on the output capacitor. Thus, the proposed converter can achieve high step-up voltage gain with appropriate duty ratio. Besides, the voltage spike on the main switch can be c...
