Use a simple voltage regulator circuit to provide a constant voltage to a high-side current monitor

In a typical photodiode current-monitoring application, the voltage drop between the current monitor and the avalanche photodiode (APD) varies with the temperature and current flowing through it, thereby changing the overall gain. This application note describes a regulator circuit that solves this problem by maintaining a constant voltage drop across the current monitor and APD.

SpaceX Starlink user terminal modification

Author Lennert Wouters demonstrated how to execute arbitrary code on Starlink user terminals via a custom modchip injected with voltage faults, and notified Starlink of these vulnerabilities.
Although the details are open source, the author does not sell the finished product, nor does he provide details of the modified endpoint firmware and fault injection used in the attack.
The transformation is to use a Raspberry Pi microcontroller
