Semiconductor device with feedback control

An electronic element (39′, 39, 40) having feedback control is provided by placing an inductive interposer (42) between the output connection or bus (382) and the input connection or bus (381), wherein the inductive interposer (42) forms part of a closed circuit (47) with the inductive interposer (42) substantially parallel with the output connection or bus (382) and input connection or bus (381) for a distance permitting significant inductive coupling therebetween. In a preferred embodiment, the closed circuit (47) containing the inductive interposer (42) comprises impedance ZT. By including various circuit elements (e.g., resistance, capacitance, and/or inductance) in ZT, the output-to-input feedback can be modified to advantage. This greatly increases the available design freedom, especially for power devices, such as for example, field effect, MOSFET, LDMOS. bipolar and other power devices that use substantially parallel input and output bus structures.
