This invention provides a circuit and method for sampling and transmitting telemetry data from a cochlear implant, belonging to the field of telemetry technology for cochlear implants. The method amplifies the analog signal under test using a programmable gain amplifier, converts the signal into a pulse width signal using a voltage ramp generator and comparator, and then generates a short-duration step signal on the coil via an output driver to form a ringing pattern. An external device detects the interval between the step signals to reconstruct the signal magnitude. This invention eliminates the need for an analog-to-digital converter, significantly reducing power consumption and chip area, and improving data transmission efficiency. It is suitable for telemetry systems in various implantable medical devices such as cochlear implants. This invention significantly reduces the power consumption and layout area of ​​the implanted chip and shortens the single data transmission time to 48μs, improving efficiency by approximately 10 times, making it suitable for low-power implantable devices such as cochlear implants.

This utility model discloses an electric griddle, which includes a shell, a temperature equalization component at the bottom of the inner cavity of the shell, and a locking component at the top of the inner cavity of the shell. This electric griddle optimizes the thermal management system and designs a bevel gear set driven by the handle. The bevel gear set, in conjunction with the connecting rod, drives the base plate to rotate. The heating ring at the bottom of the base plate is arranged in a three-layer ring pattern with 60-degree equidistant angles. The base plate rotates and radiates heat to heat the griddle, achieving dynamic thermal compensation and reducing the temperature difference between the center and the edge of the griddle. This avoids stress concentration caused by local thermal expansion due to large temperature differences in the griddle. Secondly, a dual locking mechanism consisting of mechanical locking and magnetic fixing is designed. The mechanical locking mainly uses a wedge-shaped block to lock the griddle in conjunction with a locking block at the bottom of the griddle. The magnetic fixing uses an inner layer and a surface layer to magnetically fix the magnetic block at the bottom of the griddle. This design reduces the disassembly and assembly time compared to traditional fixed griddles, making it easier for users to disassemble and maintain.
