Abstract: A method of making an integrated circuit (IC) includes forming circuitry over a top surface of a semiconductor substrate having the top surface and an opposite bottom surface. An antenna is formed in an interconnect layer formed above the semiconductor substrate, where the antenna is coupled to circuitry. A seal ring is formed around a periphery of the interconnect layer. The seal ring is disposed around the antenna and the circuitry. A trench with a solid-state insulating material is formed. The trench extends vertically into the semiconductor substrate and extends laterally across the IC.

Abstract: A track regulator circuit includes an input terminal for receiving an input signal, an output stage with an output terminal for applying an output signal to a load, an error amplifier coupled to the input terminal, and a feedback resistor between the output terminal and the error amplifier for transferring to the error amplifier a feedback signal indicative of the output signal. The error amplifier is configured for driving the output stage as a function of the difference between the input signal and the output signal so that the output signal tracks the input signal. The circuit includes a current generator coupled to the feedback resistor for injecting into the feedback resistor a soft-start current to unbalance the error amplifier, with the intensity of the soft-start current gradually ramping down to zero.
