FET protection of GMR and TMR sensors
Abstract
TMR and GMR sensors used for reading data written on magnetic media can be damaged by ns wide pulses below 1 Volt. Since diodes turn on around 1 V, they offer little ESD protection. This paper explores the use of diode-connected FETs to protect MR sensors below 1 V.
