SEMICONDUCTOR PICKUP OF MAGNETIC FIELD Russian patent published in 1996 - IPC

FIELD: electronics. SUBSTANCE: invention can be used in electronic devices for measurement of magnetic parameters of environment. Semiconductor pickup includes two sources 1,2 of constant voltage connected in parallel, field-effect transistor 3, bipolar transistor 4. Field-effect transistor is used as capacitive element of measuring oscillatory circuit formed by placement of network composed of passive inductance 5 and capacitor 6 in parallel to bipolar transistor. Bipolar transistor is inductive element of oscillatory circuit. EFFECT: improved operational stability. 1 dwg
