Analog front end electronics are designed in 65 nm CMOS technology to process charge pulses arriving from a tactile sensor array. This is accomplished through the use of charge sensitive amplifiers and discrete time filters with tunable clock signals located in each of the analog front ends. Sensors were emulated using Gaussian pulses during simula...

Evolvable hardware is a field of study exploring the application of evolutionary algorithms to hardware systems during design, operation, or both. The work presented here focuses on the use of field programmable gate arrays (FPGAs), a type of dynamically reconfigurable hardware device typically used for electronic prototyping in conjunction with a ...
A control chip with a multistage flow-rate regulation function based on the correlation between the flow resistance and flow rate has been developed in this article. Compared with the traditional proportional solenoid valve, this kind of flow valve based on microfluidic technology has the characteristics of being light-weight and having no electric...
New materials and optimized fabrication techniques have led to steady evolution in large area electronics, yet significant advances come only with new approaches to fundamental device design. The multimodal thin-film transistor introduced here offers broad functionality resulting from separate control of charge injection and transport, essentially ...

Estimating the frequency and phase of a signal is a fundamental problem in signal processing and communication. Extended Kalman Filter (EKF) is one of the approaches, and most of the implementations are in digital technologies. The fast frequency estimator (FFE), as an application of extended Kalman Filter, is an analog circuit which can determine ...
