Universal Switched-Current Integrator Blocks for SI Filter Design

The switched-current (SI) circuit is a circuit technique which is able to realize analog sampled-data circuits with a standard CMOS technology. Among all the basic SI circuits, the memory cell circuit is the most primitive element. In this work, a practical SI memory cell which employs negative feedback circuitry and glitch reduction technique is first presented. Based on this basic cell, a uni...

Low-voltage current-mode integrator for channel selection filter

A low-voltage current-mode integrator is presented for a continuous-time baseband channel selection filter of wireless communication systems. Fully-balanced current-mirror structure with additional cascode transistors operated in linear region enables low-voltage and low-power dissipation properties as well as voltage-controllable cutoff frequencies over a broad frequency range. A channel selec...

Off-axis Electron Cyclotron Current Drive for Current Profile Control in Tokamaks*

Steady-state operation in a tokamak requires full noninductive support of the plasma current. Known methods of driving noninductive current are too inefficient to support more than a small fraction of the total plasma current. The route to a steady state tokamak lies through the Advanced Tokamak approach, for which improved confinement and stability support the plasma pressure at reduced plasma...

Electron cyclotron current drive efficiency in an axisymmetric tokamak

The neoclassical transport theory is applied to calculate electron cyclotron current drive (ECCD) efficiency in an axisymmetric tokamak in the low-collisionality regime. The tokamak ordering is used to obtain a system of equations that describe the dynamics of the plasma where the nonlinear ponderomotive (PM) force due to high-power RF waves is included. The PM force is produced around an elect...

Controller for Integrator Processes

A design method for PID controllers base on internal model control (IMC) principles, direct synthesis method (DS), stability analysis (SA) system for pure integrating process with time delay is proposed. Analytical expressions for PID controllers are derived for several common types of process models, including first order and second-order plus time delay models and an integrator plus time dela...
