Abstract :
The letter describes a novel switched capacitor differential integrator circuit, useful for filtering and analogue/digital conversion applications. It uses a bucket-brigade type charge transfer to eliminate operational amplifiers. This results in reduced chip area, static power and noise. Enhancement-type NMOS transistors and MOS capacitors are used and only a single power supply is required.
