STEP 0: Pre-Calculation Summary

Formula Used

Capacitance Offpath = Total Capacitance Seen by a Stage-Capacitance Onpath
C_offpath = C_t-C_onpath
This formula uses 3 Variables

Variables Used

Capacitance Offpath - (Measured in Farad) - Capacitance Offpath is defined as the capacitance of the off-path capacitance of the logic gate.
Total Capacitance Seen by a Stage - (Measured in Farad) - Total capacitance seen by a stage is defined as the total capacitance of the stage of on and off.
Capacitance Onpath - (Measured in Farad) - Capacitance Onpath is defined as the capacitance along the analyzing path.

STEP 1: Convert Input(s) to Base Unit

Total Capacitance Seen by a Stage: 12 Picofarad --> 1.2E-11 Farad (Check conversion here)
Capacitance Onpath: 3.2 Picofarad --> 3.2E-12 Farad (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula
