WebJan 5, 2013 · 81 1 1 2. The underlying concept here is "high-side switching" vs "low-side switching". N-MOSFETs are controlled by Vgs. Their circuit is such that N-MOSFETs work as low-side switches. Your circuit is a high-side switch i.e. the source pin in N-MOSFET is not grounded and may have an unpredictable voltage. – akhmed. http://www.pldworld.com/_hdl/4/course.ee.ust.hk/elec516/Course%20materials/Lecture7-MEMORY%20SUB-SYSTEM.ppt thickness gages mitutoyo
