The circuit shown, charges a capacitor with a constant current, but, rather than discharging the capacitor, as in prior art, which takes a high current and a finite time, the polarity of the capacitor connection is reversed by a pair of make-before-break form-C high speed electronic switches. The speed of the falling edge of the ramp, at the rail-to-rail output of the high speed opamp [A], is limited only by slew rate. The capacitor, in

To live without a soul is the literal meaning of the latin word "Dementia". And that is precisely what is happening in the shoes of dementia sufferers who are inevitably faced with the circumstances of not only losing their memory but also other cognitive abilities; and the decline interferes with daily, social and occupational functioning, which leads to personality deterioration.
Difficulties with remembering things, missing appointments, misplacing things, and often finding yourselves in situations wondering "What

INTRODUCTION: As known to persons skilled in electronics, filters have an essential role.
In fact, starting from a frequency signal, it's necessary to process it and obtain another signal having phase and amplitude according to a predetermined frequency of interest. In the telecommunications field particulary, where high amplification is necessary, a system can become critical if the filtering operation is not adeguate, and the useful information can be lost. Analog active filters have had several problems
