This means, if the actual circuit voltage is 10V, the minimum capacitor voltage I will select is 13.33V (10V/0.75). However, there is no such voltage. So, I will go to the next higher level that is 16V. Can you use 20V, 25V or even higher? The answer is yes. It
Wide-tuning range programmable threshold comparator using capacitive source-voltage shifting E. Martens, B. Hershberg and J. Craninckx A comparator circuit with a built-in programmable threshold is pro-posed. The threshold is embedded by providing different

Practical capacitors are available commercially in many different forms. The type of internal dielectric, the structure of the plates and the device packaging all strongly affect the characteristics of the capacitor, and its applications. Values available range from very low (picofarad range; while arbitrarily low values are in principle possible, stray (parasitic) capacitance in any circuit is th…

15 · Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage. Quantitatively, the energy stored at a fixed voltage is captured …
Differential variable capacitors also have two independent stators, but unlike in the butterfly capacitor where capacities on both sides increase equally as the rotor is turned, …
The position measurement is based on differential capacitance sensors and capacitance to voltage converters (CVCs), and aims at detecting the motion of a …

The amplifier has a differential gain of 1000 and a highpass cutoff frequency of 2.3 Hz, and it can handle a differential-input dc-voltage range of ±0.34V. To obtain this performance, you set the active-feedback stage gain and the differential-amplifier gain, respectively, to 67.6 and 15.
Capacitive source shifting: In this Letter, we propose to implement the source-voltage shift using a charge-redistribution capacitor DAC. One such circuit is shown in Fig., where we use a step-down DAC and a two-stage comparator, though other DAC and
Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up to that voltage.
