Drift in switched-capacitor integrators

Microelectronics Journal, 1984
Imperfections in MOS devices which cause drift over time in the output voltage of a switched-capacitor integrator include junction leakage, offset voltages, charge pumping, and charge-injection (clock feedthrough) from the switches. The origins of these imperfections and techniques to minimise their effect are discussed.

An improved switched-capacitor integrator

Electronics Letters, 1978
A novel switched-capacitor integrator is described which results in the mapping of the analogue frequency axis directly on the unit circle of the z-plane. The circuit requires one extra capacitor and additional switches. It makes the design much easier and doubles the effective sampling rate.

Novel stray-insensitive switched-capacitor integrator

Electronics Letters, 1980
A stray-insensitive switched-capacitor integrator is introduced which enables the design of leapfrog filters suitable for high clock/signal frequency ratios without causing large capacitor spreads. A design example is given.

Influence of gate tunneling currents on switched capacitor integrators [PDF]

Advances in Radio Science, 2009
In order to achieve a higher level of integration in modern VLSI systems, not only the lateral geometrical dimensions have to be scaled. Lowering the supply voltage also requires scaling down the oxide thickness of the transistors.

MOS switched capacitor integrator eliminating operational amplifiers

Electronics Letters, 1981
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.

Organic Electrochemical Transistor Channel Materials: Copolymerization Versus Physical Mixing of Glycolated and Alkoxylated Polymers

Advanced Functional Materials, EarlyView.
This work discusses the use of blended channel materials in OECTs. It explores how mixing glycolated and alkoxylated polymers in various ratios offers a simpler and more efficient route to tuning OECT properties. The performance of the polymer blends is compared to the corresponding copolymers, demonstrating similar OECT characteristics, swelling ...

NanoMOF‐Based Multilevel Anti‐Counterfeiting by a Combination of Visible and Invisible Photoluminescence and Conductivity

Advanced Functional Materials, EarlyView.
This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
