Reset circuit

Abstract

PURPOSE:To avoid a faulty working of MOS-IC, by generating the reset pulse after detecting a voltage change of the power supply at the power supply from the source for the MOS-IC and then resetting the floating node of MOS-IC. CONSTITUTION:When the power supply voltage VCC is applied and reaches to the value VCC higher than the threshold voltage of MOST of Q11 and Q13, the potential starts rising for the node N1 and reset output signal phi1. When N1 reaches the threshold voltage of Q14, the Q14 is turned on to discharge phi1. Accordingly the reset output phi1 rises in the increasing course of voltage VCC and then falls when N1 reaches its threshold value.
