A simple circuit is described to make an AC-amplifier and an analog-to-digital converter in a single, compact solution, for use in basic research, but not on humans. The circuit sends data to and is powered from a common USB port of modern computers; using proper firmware and driver the communication with the device is an emulated RS232 serial port.

The horn loudspeaker suffers from producing high distortions. Based on an physical model an equivalent lumped parameter circuit is determined for a horn loaded compression driver. From the nonlinear differential equation of this circuit, a compensation algorithm is implemented on a Digital Signal Processor (DSP) for reducing nonlinear distortion caused by the behaviour of air. Test results are ...

In this paper, we propose a five-transistor (5T) static random access memory (SRAM) that can be read and written reliably with the assistance of read/write circuits. The read/write circuits include a voltage control circuit, a pre-charging circuit and a standby start-up circuit. The voltage control circuit is connected to the sources corresponding to driver transistors of each row memory cells....

— This paper proposes a new circuit for capacitive sensing based on Dickson's charge pump. The proposed touch sensing circuit includes three stages of NMOS diodes and capacitors for charge transfer. The proposed circuit which has a simplified capacitive touch sensor model has been analyzed and simulated by Spectre using Magna EDMOS technology. Looking from the simulation results, the proposed c...

A circuit for generating reference voltages for an A/D converter is presented. The circuit consisting of a bandgap reference and a driver circuit is capable of operating on sub 1-volt supply voltages. The circuit is designed using a standard 0.5 m CMOS technology. Simulations show maximum 0.24% variation in the generated reference voltage over a temperature range from -20 C to 100C and a supply...
