James Clerk Maxwell used switches and a capacitor to measure the equivalent resistance of a galvanometer in the 1860''s. Parallel Switched Capacitor Equivalent Resistor: i (t) i (t) 2 v (t) 1 v (t) 2 1 R (b.) Figure 9.1-1 (a.) Parallel switched capacitor equivalent
EXAMPLE 9.1 -Design of a Parallel Switched Capacitor Resistor Emulation If the clock frequency of parallel switched capacitor equivalent resistor is 100kHz, find the value of the capacitor C that will emulate a 1MΩ resistor.
Based on MOSFETs and capacitors, a switched-capacitor convertor (SCC) can effectively realize step-down or step-up conversion by switching serial-to/from-parallel connection and phase modulation.
Analyzing the charge across the capacitors in each phase, and considering that the output of the circuit will again be sampled at the end of phase φ 1, Table 2.3 is obtained. Capacitance (C_{p1}) represents the bottom plate parasitic capacitance of (C_{R1}) and the parasitic capacitances of the switches connected to the bottom plate of …
Why Switched-Capacitor? •Used in discrete-time or sampled-data circuits. Alternative to continuous-time circuits. •Capacitors instead of resistors. Capacitors won''t reduce the …
When the switch closes, the inrush current flows from the source to charge the capacitance. The inrush current affects the whole system from the power source to the capacitor …

19.5: Capacitors and Dielectrics
The complex behavior and history dependence of a ferroelectric capacitor in response to arbitrary voltage patterns can be well described by a parallel-elements …
Parallel grouping of capacitors is shown below and is analogous to the connection of resistance in parallel or cells in parallel. Parallel Combination of Capacitors When capacitors are connected in parallel, the total capacitance is the sum of the individual capacitances, because the effective plate area increases.
impedance.,, the greater part of is connected in parallel with *, reducing the impedance of the power distribution system as seen from the load of the power supply ) +*.The value of a parasitic capacitance is typically much smaller than a decoupling capacitor such as
If a circuit contains a combination of capacitors in series and parallel, identify series and parallel parts, compute their capacitances, and then find the total. 4.8: Capacitors in Series and Parallel is shared under a CC BY 4.0 license and was authored, remixed, and/or curated by LibreTexts.
