8. τ = kR_xC_x and k = 0.7 for the output pulse width corresponding to R_x = 10 kW, C_x = 0.1 mF.
9. τ = kR_xC_x and k = 0.79 for the output pulse width corresponding to R_x = 100 kW, C_x = 1 nF.
10. Pulse width match variation between ICs (part−to−part) is defined with identical R_x, C_x, V_CC and a specific temperature.
