Abstract
Transient blocking unit reset capability is improved by adding one or more transistors in parallel to one of the main blocking transistors of the circuit. These additional transistors switch off at higher voltages than their corresponding main blocking transistor, and have higher on-resistances than their corresponding main blocking transistor. The resulting transient blocking unit characteristic has two or more different slopes in the negative differential resistance part of the circuit I-V characteristic. This piecewise linear behavior can be exploited to ensure that the circuit I-V characteristic only has a single intersection with a normal load characteristic. By satisfying this condition, automatic reset is ensured, because the combination of the transient blocking unit with any load that is consistent with the normal load characteristic will have only one stable operating point.
