Magnetic energy per particle in constant current density
We assume a constant current density in a homogeneous one-component plasma of infinite extent and calculate the resulting magnetic energy per particle. Our starting point is the conserved approximately relativistic (Darwin) energy for a system of electromagnetically interacting particles that arises from the neglect of radiation. For the idealized model of a homogeneous one-component plasma the...
متن کاملTitle An LED Drive Circuit with Constant - Output - Current Control andConstant - Luminance Control
A Single LED is very small, and their luminance is related to the amount of driving current. Sufficient luminance for an illuminator requires many LEDs to be connected together and a constant current supplied to each LED. Therefore, the LED drive circuit must have constant-output-current control and/or constant-luminance control. We propose an LED drive circuit that consists of a boost-type DC-...
متن کاملINTEGRATED CIRCUIT DEVICE MISMATCH MODELING AND CHARACTERIZATION FOR ANALOG CIRCUIT DESIGN by
This work presents a new method for the modeling and characterization of resistor, MOSFET and bipolar transistor mismatch for analog circuit design. For transistors, sensitivities numerically calculated from SPICE models were used to infer mismatch variances in process parameters, such as sheet resistance and geometry variation, from electrical parameter mismatch variances, such as collector cu...
متن کاملArithmetic Constant-Depth Circuit Complexity Classes
The boolean circuit complexity classes AC ⊆ AC[m] ⊆ TC ⊆ NC have been studied intensely. Other than NC, they are defined by constant-depth circuits of polynomial size and unbounded fan-in over some set of allowed gates. One reason for interest in these classes is that they contain the boundary marking the limits of current lower bound technology: such technology exists for AC and some of the cl...
متن کاملNon-quasi-static modeling/implementation of BJT current crowding for seminumerical mixed-mode device/circuit simulation
VLSI technology CAD (TCAD) requires integrated, physics-based tools for predictive process, device, and (small-scale) circuit simulation. Computational efficiency is desirable, and indeed essential if the TCAD system is to be used in manufacturing CAD involving statistical simulation. Conventional TCAD systems comprise robust, numerical process and device simulators which drive optimization of ...
