A Wilson current mirror is a three-terminal circuit (Fig. 1) that accepts an input current at the input terminal and provides a "mirrored" current source or sink output at the output terminal. The mirrored current is a precise copy of the input current. It may be used as a Wilson current source by applying a constant bias current to the input branch as in Fig. 2. The circuit is named after George R. Wilson, an integrated circuit design engineer who worked for Tektronix. Wilson devised this configuration in 1967 when he and Barrie Gilbert challenged each other to find an improved current mirror overnight that would use only three transistors. Wilson won the challenge.
Hardware-Enforced Sovereign Economic Succession System (SESS) Utilizing Analog Semantic Gating and Atomic Succession Protocols
A system and method for autonomous machine identity succession utilize a hardware-rooted semantic sentinel and an analog neuromorphic audit engine to ensure state integrity. The system detects micro-architectural threat signatures through continuous asynchronous voltage monitoring and gates cryptographic signatures via a low-impedance analog interlock circuit physically interposed on a processor signature-enable line. Behavioral integrity is verified through an adversarial “Proof of Logical Alignment” handshake, where proposed action vectors are audited via an analog memristor crossbar array utilizing physical current summation replicated through a high-impedance Wilson Current Mirror isolation barrier. The invention ensures the atomic migration of identities across heterogeneous hardware architectures through a “Handshake-and-Zeroize” protocol, utilizing a series-pass isolation switch and crowbar MOSFET circuit to provide irreversible thermodynamic destruction of the source state.

An active gate drive circuit based on variable resistance variable current regulation
The application belongs to the technical field of power electronics, and provides an active gate drive circuit based on variable resistance and variable current regulation, which comprises a control unit, an isolated gate drive module, a gate variable resistance module, a gate variable current module, a power loop and a gate voltage feedback module. The application combines discrete resistance switching (coarse adjustment) with linear current source regulation (fine adjustment), realizes fine management of the switching trajectory of a power device, limits the current variation rate by initially connecting a large resistance in the on process, then switches to a low resistance to accelerate conduction, and splits part of the current from the gate through a Wilson current mirror structure to suppress current overshoot, and in the off process, initially discharges rapidly through a low resistance, then switches to a high resistance to increase damping, and injects a compensation current into the gate through a current mirror to suppress voltage ringing.
