An electronic contact lens. In some embodiments, the electronic contact lens includes: a power management circuit; and a first cell, the power management circuit including an active switch, the active switch being configured to isolate the first cell from other contact lens elements when the power management circuit is powered down.

Isolation control circuit for an electronic contact lens

An electronic contact lens. In some embodiments, the electronic contact lens includes: a receiver, including: a voltage-controlled oscillator; a phase-alignment circuit, connected to a control input of the voltage-controlled oscillator; and an offset-compensating circuit, connected to the control input of the voltage-controlled oscillator, the receiver being configured: to operate in: a calibration mode, or an operating mode; and to select, in the calibration mode, an operating-mode setting of the offset-compensating circuit, the selecting including: adjusting the offset-compensating circuit, and monitoring an output frequency of the voltage-controlled oscillator.

Electronic contact lens data receiver circuit

A micro-LED display has an array of separately controllable micro-LEDs and corresponding pixel drivers. The pixel drivers have pulse-width modulation (PWM) generator circuits for the LEDs. The PWM generator circuits include the following. N input nodes are coupled to receive N control bits that determine a brightness of the LEDs. An output node is coupled to output the drive signal to the LEDs. Each of N transistors are connected between one of the input nodes and the output node. Each transistor is controlled by a clock signal CKand couples the input node to the output node as controlled by the clock signal CK.

Compact pixel driver for micro-LED displays

An electronic contact lens. In some embodiments, the electronic contact lens includes a plurality of power-consuming circuits and a power supply circuit. The power supply circuit may be configured to distribute available power among two voltage domains in the electronic contact lens according to changing power requirements within the two voltage domains.

Contact lens power supply with movable generator

A contact lens battery management system (BMS) monitors battery health in an electronic contact lens. A battery made with high-internal-resistance cells is coupled on a cell-by-cell basis to input switches of a power management integrated circuit (PMIC) that monitors, detects, and isolates faulty circuit components.
