STEP 0: Pre-Calculation Summary
Formula Used
Adjacent Capacitance = (Victim Voltage*Ground Capacitance)/(Agressor Voltage-Victim Voltage)
This formula uses 4 Variables
Variables Used
Victim Voltage - (Measured in Volt) - Victim Voltage is calculated when the victim being actively driven, then the driver will supply current to oppose to reduce the victim's noise.
Ground Capacitance - (Measured in Farad) - Ground Capacitance is the capacitance at the ground of the CMOS Circuit.
Agressor Voltage - (Measured in Volt) - Agressor Voltage refers to the avoided voltage in a CMOS circuit, which is typically a small positive voltage added to the input signal to avoid unwanted triggering of the circuit.
STEP 1: Convert Input(s) to Base Unit
Victim Voltage: 12.75 Volt --> 12.75 Volt No Conversion Required

## How does noise vary with victim and the aggressor?

Suppose wire A switches while B is supposed to remain constant. This introduces noise as B partially switches. We call A the aggressor or perpetrator and B the victim. t when the victim is floating, the noise remains indefinitely. When the victim is driven, the driver restores the victim. Larger (faster) drivers oppose the coupling sooner and result in noise that is a smaller percentage of the supply voltage. Note that during the noise event the victim transistor is in its linear region while the aggressor is in saturation. For equal-sized drivers, this means Raggressor is two to four times Rvictim, with greater ratios arising from more velocity saturation.

## How to Calculate Adjacent Capacitance?

Adjacent Capacitance calculator uses Adjacent Capacitance = (Victim Voltage*Ground Capacitance)/(Agressor Voltage-Victim Voltage) to calculate the Adjacent Capacitance, The Adjacent capacitance formula is defined as the capacitance that is adjacent to the node Ae wire A switches while B is supposed to remain constant. Adjacent Capacitance is denoted by Cadj symbol.
