AI Technical Summary
Existing wake-up receivers suffer from high power consumption and poor reliability when temperature changes, and their integration is not high, making it difficult to meet the low-cost and high-reliability requirements of IoT nodes.
Impedance matching is achieved using a high-Q MEMS acoustic resonator. Combined with a low-temperature drift clock module, a reference current source, and a threshold-adjustable dynamic comparator, a low-temperature drift DC level boosting circuit and a fully differential baseband amplifier are designed, and the chip packaging structure is optimized.
It achieves low power consumption, low noise figure and high sensitivity over a wide temperature range, significantly reduces chip area and improves system temperature stability and integration.
