Improved switched-capacitor algorithmic analogue-to-digital convertor
Electronics Letters, 1985 A novel switched-capacitor circuit is presented for algorithmic analogue-to-digital conversion. Besides the reduced component count, the proposed circuit shows that it can accept a differential analogue signal. A conversion accuracy higher than 12 bits is easily attainable with its integrated version.

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.
