Abstract: Reference center circuitry for a metrology system is disclosed. In one embodiment, the circuitry includes a reference sensor having a topology and characteristics identical to a number of sensors throughout an IC. The both the reference sensor and the sensors on the IC may be used to perform voltage and temperature measurements. The reference sensor may receive a voltage from a precision voltage supply, and may be used as a sensor to provide a basis for calibrating the other sensors, as well. Thereafter, temperature readings obtained from the other sensors may be correlated to the readings obtained by the reference sensor for enhanced accuracy. The reference center circuitry also includes analog process monitoring circuitry, which may be coupled to some, if not all of the transistors implemented on an IC.

Abstract: Methods, systems, and apparatuses for charging a host device from a charging source through an accessory are described. Upon detecting an input power signal from the charging source, an accessory may send an identification request to the host device and authenticate the host device based on the identification information received from the host device. Upon authenticating the host device, the accessory may enable a power path between the charging source and the host device to supply a charging current to charge the host device.

Abstract: A reference voltage generation circuit (or bandgap circuit) having a flipped-gate transistor is disclosed. A bandgap circuit according to the disclosure includes first, second, third and fourth transistors. The first transistor is a flipped-gate transistor having a gate terminal of an opposite polarity (e.g., an n-channel metal oxide semiconductor, or NMOS, transistor having a gate terminal with a p-type polysilicon implant). The second third and fourth transistors have a corresponding type polysilicon implants (e.g., NMOS transistors having respective gate terminals with an n-type polysilicon implant). The circuit is configured to generate a reference voltage equal to a sum of gate-source voltages of the first and third transistors, minus respective gate-source voltages of the second and fourth transistors.

Abstract: An adapter for connecting an accessory to a portable electronic device includes a first connector compatible with a connector of the portable electronic device and a second connector compatible with a connector of the accessory. The connectors of the accessory and the portable electronic device are otherwise incompatible with each other. The adapter provides two levels of authentication. First, the adapter authenticates itself to the portable electronic device. If this first authentication is successful, then the adapter authenticates the accessory to the adapter.
