Tunable microstrip resonators with ferroelectric capacitors
Radioelectronics and Communications Systems, 2010The question of increasing the tuning band of microstrip resonators that use ferroelectric capacitors for tuning in the region of increased electric lengths is considered which allows using them in the upper part of the centimeter band (Ku-band, K-band). Band properties of regular and step-irregular resonators operating at the lowest resonant frequency

Properties of Tunable Filters with Ferroelectric Capacitors
Integrated Ferroelectrics, 2002The range of a tunability of the filter with ferroelectric capacitor is determined by the commutation quality factor (CQF), which takes into account both the tunability of the capacitor under biasing voltage and the loss factor. For effective tuning, the CQF should be high enough (more than 1000).

Modeling ferroelectric capacitors for memory applications
IEEE Circuits and Devices Magazine, 2002The ferroelectric capacitor model is the foundation for accurate simulation of ferroelectric hysteresis loops and minor loops, transitions between the loops under arbitrary voltage patterns, transient responses of ferroelectric capacitors to short voltage pulses with widths in the nano-second range, and temperature behaviors of ferroelectric capacitors.

Thin film ferroelectrics for capacitor applications
Journal of Materials Science: Materials in Electronics, 1998Pulsed laser deposition (PLD) has been used to fabricate simple thin film capacitor structures with a variety of ferroelectric materials. Thin film capacitors using the conventional ferroelectric material BaxSr1-xTiO3(BSTO) have been made across the entire compositional series.

A survey of behavioral modeling of ferroelectric capacitors
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1997Six different behavioral models for ferroelectric capacitors are surveyed with an emphasis on their usefulness in the transient circuit simulation of integrated nonvolatile memories. These models can be broadly classified into two categories, namely, those that rely on the hysteresis loop and those that rely on the switching current of a ferroelectric ...

3D Vertical Ferroelectric Capacitors with Excellent Scalability
Nano LettersThree-dimensional vertically stacked memory is more cost-effective than two-dimensional stacked memory. Vertically stacked memory using ferroelectric materials has great potential not only in high-density memory but also in neuromorphic fields because it secures low voltage and fast operation speed.

Cryogenic Characteristics of Ferroelectric Capacitors and Ferroelectric Field-Effect Transistors
ECS Meeting AbstractsFerroelectricity exhibits two stable states with permanent polarizations, making it promising for nonvolatile memory applications. Compared to conventional perovskite ferroelectrics, hafnium-based ferroelectric materials, such as Hf0.5Zr0.5O2 (HZO), attracts much attention due to their compatibility with CMOS technology [1].
