| Features |
Circuit The reset signal is designed to be Low at initial powerup and become High shortly after VCC reaches its normal operating voltage. Assume the VCC rail has been at 0 V for some time so that capacitors C1 and C2 are completely uncharged and then VCC is applied. It can be seen that initially the gate of the n-channel transistor T1 will still have 0 V applied to it (due to the uncharged state of C1) and will therefore be turned off. C2 is also uncharged, but since one plate of this capacitor is now at +5 V, the input to the inverter will also be at +5 V. The output of the inverter will the... |
