- Abstract
- A real-time capacitor compensation (RCC) scheme is proposed for low power wearable inductive coupling transceiver. To compensate for the dynamic parameter variations in real time, the inductance value is monitored and its resonance Frequency is adjusted by additive capacitors. RLC bridge for detection of the inductance variations and the dual-edge sampling comparator for recognition of the variance direction are proposed. The proposed transceiver consumes only 426.6 mu W (102.6 mu W for TRX and 324 mu W for CDR) in a 0.18 mu m CMOS technology. And the compensation time takes only 4.78 mu s, including 3 mu s of detection and 1.78 mu s for compensation process in worst case.
