The free programmable analog arrays (FPAA) circuits allow the using of dynamically reconfigurable analogue electric circuits that are most suitable for the desired functions. This is of major importance in the case of wide area of the using of analog circuit in any place of the electronic. From other spot we can say by the help of the FPAA and microcontroller (MCU) we can generate-, and/or fine...
This paper benchmarks a midrange MCU from Microchip (dsPIC33FJ family) used as a controller for a magnetic levitation plant. Basic control algorithms (slightly modified PID and State Space) are tested to present a rough idea of how long it takes to compute one iteration of the control algorithm loop. Beside this, the significance of various optimisation parameters for the code generation proces...
Applications involving processing of signals from external analog sources/sensors usually require some kind of digital filtering. For extremely high filter performance, Digital Signal Processors (DSP) are usually chosen, but in many cases these are too expensive to use. In these cases, 8and 16-bit Microcontrollers (MCU) come into the picture. They are inexpensive, efficient, and have all the re...
Continuous processes have been controlled by feedback loops since the late 1700’s. In 1788, James Watt used a flyball governor on his steam engine to regulate its speed. The Taylor Instrument Company implemented the first fully functional Proportional, Integral and Derivative (PID) controller in 1940. Although feedback control has come a long way since James Watt, the basic approach and system ...
• The on-chip op amp of the PIC16F785 is used to amplify the voltage across the current sensing resistor. This allows a much smaller sensing resistor to be used and reduces power dissipation. • The PIC16HV785 device can be used, which eliminates the requirement for an external 5V regulator when operating from higher supply voltages. • This application has unused analog resources which could be ...
Mitochondrial calcium (Ca(2+)) import is a well-described phenomenon regulating cell survival and ATP production. Of multiple pathways allowing such entry, the mitochondrial Ca(2+) uniporter is a highly Ca(2+)-selective channel complex encoded by several recently-discovered genes. However, the identity of the pore-forming subunit remains to be established, since knockdown of all the candidate u...
The conference series Machines, Computations and Universality (MCU) explores computation in the setting of various discrete models, such as Turing machines, register machines, cellular automata, tile assembly systems, rewriting systems, molecular computing models and neural models, and in the setting of analog and hybrid models, including BSS machines, signal machines and quantum computing, to ...
We propose a circuit to directly connect a differential capacitive sensor to a microcontroller unit (MCU), which is based on the charge-transfer method and does not need any calibration component. The performance has been tested by emulating the differential capacitive sensor with discrete components. The major uncertainty sources are residual stray capacitances. The maximal deviation obtaine...
Approximately one-third of embedded designers surveyed on the adoption and use of FPGAs for embedded applications responded that they perceived FPGAs as too expensive to use in their designs. However, a look at the total cost of ownership (TCO) at the system level (as measured by development, enhancement, replacement, and maintenance costs over the lifetime of the product) reveals that Altera® ...
