In electronics, a latch-up is a type of short circuit which can occur in an integrated circuit (IC). More specifically, it is the inadvertent creation of a low-impedance path between the power supply rails of a MOSFET circuit, triggering a parasitic structure which disrupts proper functioning of the part, possibly even leading to its destruction due to overcurrent. A power cycle is required to correct this situat… WebThe antenna arrays as seen above, are used for the improvement of gain and directivity. A parasitic element is an element, which depends on other’s feed. It does not have its own feed. Hence, in this type of arrays we …
