Some embodiments include electronic circuitry for an electronic lock. The electronic circuitry can include: an antenna configured to receive a wireless signal; a communication processor, coupled to the antenna, configured to decode the wireless signal to ascertain a command to lock or unlock the electronic lock and to authenticate a source of the wireless signal; an energy storage configured to store electrical energy; a motor switch configured to drive a motor clockwise or counterclockwise, powered by the energy storage, depending on a control signal, wherein the motor switch is configured to drive the motor for a short burst of time; and a controller, coupled to the energy storage capacitor and the motor switch, configured to monitor electrical charge left in the energy storage and to output the control signal that corresponds to the command to lock or unlock the electronic lock.

NFC or BLE based contactless lock with charge monitoring of its energy storage

A voltage reference generator for a hysteresis circuit, comprising a first originator circuit to generate a first reference voltage; a second originator circuit to generate a second reference voltage; and a selector circuit, coupled to the first and second originator circuits, to select one of the first and second reference voltages to be an output reference voltage based upon an input signal to the hysteresis circuit undertaking a low-to-high or a high-to-low signal transition respectively. The first originator circuit includes a first plurality of channel devices selected from either p-channel devices or n-channel devices and the second originator circuit includes a second plurality of channel devices selected from the other one of the p-channel devices and the n-channel devices.
