A capacitive divider is a passive electronic circuit that consists of two or more capacitors connected in series. Its primary function is to divide an AC voltage into smaller, proportional voltages across each capacitor. The voltage division occurs based on the capacitance values of the individual capacitors in the circuit.
Similar to a voltage divider circuit using resistors, capacitors are connected in series to form a voltage divider network with a voltage source. How to Work Capacitive Voltage Divider?
A frequency compensated voltage divider or attenuator is a simple two-port RC network providing a fixed voltage division ratio or attenuation over a wide frequency range and not just at dc. Such networks are used where the part of the circuit loading the voltage divider output is capacitive.
However, it’s crucial to note that unlike resistive dividers, the voltage division ratio in a capacitive divider varies with frequency due to the frequency-dependent impedance of capacitors. Consider a simple capacitive voltage divider circuit consisting of two capacitors, C1 and C2, connected in series across a voltage source Vin.
Impedance Matching: Capacitive voltage dividers can also be used in impedance matching applications to maximize power transfer. Limitations: On the downside, capacitive dividers are not suitable for DC applications because capacitors block DC current.
Frequency Dependence: The voltage division ratio of a capacitive divider is frequency-dependent due to the variation in capacitive reactance with frequency. This means that the output voltage will vary with the frequency of the input signal.
