Abstract: A current sensor (10) for detecting AC current through a load impedance (14) of an electrical circuit. Sensor components are fabricated within a multilayer board (fig. 3). The sensor includes a transformer circuit including a primary coil (32) coupled in series with the current path (16, 18) of the electrical circuit. The primary coil (32) includes current path elements (20A, 20B) in the form of conductive strips. The transformer secondary (30) comprises first and second electrically conductive coils (30a, 30b) inductively coupled to the current path. The secondary coils are electrically connected in series with one another, so that voltages generated across the coils in response to current in the current path are additive, while interference voltages which are induced in the coils by the presence of external magnetic fields or cross talk between adjacent sensors on the same board are cancelled.

Abstract: An integrated circuit has at least two components described in the form of two ideally matched transistors, each of which operate interdependently as a function of temperature and at least one physical parameter associated with each of said components when implemented in integrated form. The circuit further includes compensation means (Q9-Q16, R2-R4), disposed in the integrated circuit, for generating and applying a bipolar compensation signal (Isym) to at least one of said components (Q6) so that said two components interdependently operate predictably, consistently and independently of temperature variations and differences between the physical parameter of said two components. The bipolar current is necessary so that both the level and polarity of the compensation signal can be appropriately adjusted during the manufacture of the integrated circuit as a wafer so as to eliminate the need to compensate for any mismatches in the two components following such manufacture.
