A novel topology for a high gain two-stage amplifier is proposed. The proposed circuit is designed in a way that the non-dominant pole is at output of the first stage. A positive capacitive feedback (PCF) around the second stage introduces a left half plane (LHP) zero which cancels the phase shift introduced by the non-dominant pole, considerably. The dominant pole is at the output node which m...

Fluoride (F), a powerful oxidizing agent, is used in a variety of industries in China. Health problems among industrial workers due to F poisoning are on the rise. Long-term F exposure, together with varieties of relevant factors, leads to high F burden [blood fluoride (BF), urinary fluoride (UF)], which can finally result in F bone injury (1). As F burden is the major cause of F bone injury, t...

A multistage operational transconductance amplifier with a feedforward compensation scheme which does not use Miller capacitors is introduced. The compensation scheme uses the positive phase shift of left-half-plane (LHP) zeroes caused by the feedforward path to cancel the negative phase shift of poles to achieve a good phase margin. A two-stage path increases further the low frequency gain whi...

For a new kind of automatic transmissions using proportional pressure valves to control the clutches directly, a two-degree-of-freedom controller is designed for clutch slip control during the inertia phase of the shift process. The controller is designed based on a low order linear model which is derived from dynamics of the proportional pressure control valve and the vehicle drive line. The f...

We show that if f is a transcendental meromorphic function with a finite number of poles and f has a cycle of Baker domains of period p, then there exist C > 1 and r0 > 0 such { z : 1 C r < |z| < Cr } sing(f−p) ∅, for r r0. We also give examples to show that this result fails for transcendental meromorphic functions with infinitely many poles.

this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...
