Model variable capacitor
RF Blockset / Circuit Envelope / Elements
The Variable Capacitor block controls the output of RF Blockset™ feedback circuits using Simulink® controlled capacitance in farads. The minimum value of the capacitance (Cmin) is a RF Blockset defined constant independent of the Simulink control signal. The block has two electrical terminals. One terminal is for the Simulink control signal and one terminal is for the RF Blockset signal.
C— Simulink control signal
Simulink control signal, specified as a scalar.
The Variable Capacitor block has no parameters.
Behavior changed in R2021b
Starting in R2021b, the Variable Capacitor block icon is now updated. When you open a model created before R2021b containing a Variable Capacitor block, the software replaces the block icon with the R2021b version.
