A neural network approach is presented for modeling and characterization of on-chip copper spiral inductors. The approach involves the creation of neural network models to map 3D multi-level spiral inductor geometric characteristics to SPICE equivalent circuit parameters. The neural network replaces computationally expensive FEM-based extraction and field solution. The approach is especially at...
In this paper a single-inductor dual-output (SIDO) buck-boost PFC converter operating in critical conduction mode (CRM) is proposed. By multiplexing a single inductor, each output of SIDO buck-boost converter can be regulated independently. Compared with conventional two-stage multiple output converter, SIDO buck-boost PFC converter benefits from significant overall cost saving, small size and ...
This paper presents the design of five-stage current controlled inductor-less ring oscillator that were simulated in Silterra 0.18um CMOS Technology with oscillation frequencies up to 5.99 GHz. The design uses cross coupled MOS devices along with active inductor (thus inductorless) and controlled by current source to aid in switching speed and to improve the noise parameters. The simulations sh...
It is well known that a °oating inductor circuit is realized from a grounded inductor circuit by replacing the operational ampli ̄er by a °oating operational transconductance ampli ̄er. This idea is extended to transform current conveyor grounded inductors to °oating inductors by replacing the current conveyor by the recently introduced °oating current conveyor. Several examples are considered an...
On-chip inductors are critical for enabling portable power-efficient wireless communication systems. Existing on-chip spiral inductors based on conventional planar integrated-circuit fabrication technology suffer from substrate loss and parasitics, and have relatively large footprints. In this paper, we discuss the development of two types of on-chip three-dimensional (3-D) inductors—a vertical...
This chapter deals with the design methodologies to obtain DC-DC converters with multiple outputs and only one inductor. The four possible schemes, buck, boost, and inverting or noninverting buck-boost, are considered. The key specific problems related to the issue are the inductor current switching scheme, the multiple-loops control, the suitable driving of power switches and, accordingly, the...
The Conventional Boost Converters is not possible to obtain the high voltage gain. In this paper a DCDC boost converter is proposed for achieving high voltage gain and to reduce the harmonic content in the output side. The circuit diagram of the proposed converter is consists of coupled inductor. Therefore the voltage stress on the active switch is reduced due to the presence of the inductor an...
We study the dynamical equations of nonlinear inductor-capacitor circuits. We present a novel Lagrangian description of the dynamics and provide a variational interpretation, which is based on the maximum principle of optimal control theory. This gives rise to an alternative method for deriving the dynamic equations. We show how this generalized Lagrangian description is related to generalized ...
We report the first nanofluidic inductor (L) to complement the known nanofluidic capacitors (C), resistors (R), and diodes for ion currents. Under negative bias, the nanopore behaves like a parallel RC circuit at low frequencies; however, under positive bias, the asymptotic dynamics is that of a serial RL circuit. This new ionic circuit element can lead to nanofluidic RLC or diode-inductor osci...
This paper presents an approach to establish the analytical formula for the force acting on a non-magnetic disc plunged into a ferrofluid, due to the effect of a magnetic field gradient generated by the magnetic inductor of the actuator. The expression of the force acting on a magnetizable body placed in a magnetic field was used for the particular conditions imposed by the actuator configurati...
