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 ...
