A versatile all-channel stimulator for electrode arrays, with real-time control [PDF]

, 2004
Over the last few decades, technology to record through ever increasing numbers of electrodes has become available to electrophysiologists. For the study of distributed neural processing, however, the ability to stimulate through equal numbers of ...

Switched-capacitor immittance convertors using a single operational amplifier

Electronics Letters, 1980
The improved switched-capacitor immittance convertors using a single operational amplifier are proposed. The general scheme which enables the conversion of the capacitive (n + 1)-terminal networks into the corresponding bilinearly equivalent networks consisting of LC parallel branches is also proposed.

Novel capacitance-ratio-independent switched-capacitor digital-analogue convertor

Electronics Letters, 1989
A novel switched-capacitor (SC digital-to-analogue (D/A) convertor is presented which exhibits high linearity owing to a capacitance-ratio-independent conversion algorithm. The core of the convertor consists of an SC circuit which processes the digital word, bit-by-bit, by integrating the reference voltage for a number of time slots corresponding to ...

Characteristic curves for analysing limit cyclebehaviour in switching convertors

Electronics Letters, 1999
The concept of characteristic curves (CCs) for analysing the behaviour of limit cycles in elementary DC-DC switching converters is introduced. The CC is derived by considering opposite vector fields in the on and off configurations. Feedback regulated converters with PWM or hysteresis control are investigated using this approach.

A Four-Quadrant Switched Capacitor DC-DC Convertor Enabling Power-Efficient Lab-Grade Potentiostats [PDF]

2020 IEEE 20th Mediterranean Electrotechnical Conference ( MELECON), 2020
This paper presents a low-power potentiostat based on a four-quadrant switched capacitor DC-DC convertor for use in lab applications. The gearbox convertor achieves a compliance voltage of ±2.5V. Through the use of frequency scaling, the convertor features output currents in the range of 1µA to 1mA, outclassing other state-of-the-art power efficient ...

Semiconductor loss calculation of DC–DC modular multilevel converter for HVDC interconnections

High Voltage, 2018
DC–DC modular multilevel converter (DC–DC MMC) is an attractive candidate for high-voltage DC (HVDC) interconnections since it can provide the required voltage matching, galvanic isolation and flexible power control abilities.
