Switched-Capacitor Dynamic Threshold PMOS (SC-DTPMOS) Transistor for High Speed Sub-threshold Applications

This work studies the effects of dynamic threshold design techniques on the speed and power of digital circuits. A new dynamic threshold transistor structure has been proposed to improve performances of digital circuits. The proposed switched-capacitor dynamic threshold PMOS (SC-DTPMOS) scheme employs a capacitor along with an NMOS switch in order to effectively reduce the threshold voltage of ...

Distortion Correction Circuits for Audio Amplifiers*

Circuit topologies are introduced which should prove of use to the circuit designer of analog audio amplifiers. The objective is to produce circuits of' modest complexity that overcome the nonlinearities inherent in single-transistor and long-tail pair circuits. This allows amplifiers with excellent linearity to be designed without resorting to overall negative feedback with high loop gains. To...
