Abstract
- This presents a differential outputs divide-by-4 with class-A-C injection-locked frequency divider (ILFD) was implemented in the TSMC standard 0.18 μm CMOS process for biomedical sensor and wearable applications. The ILFD is based on a differential VCO with one injection MOSFET for coupling the external signal to the resonator. The locking range of the ILFD is increased by using a new LC resonator. Measurement results show that at the supply voltage of 1.5 V, the divider's free-running frequency is 3.5 GHz, and at the incident power of 0 dBm the locking range is about 3.1GHz (20.4%), from the incident frequency 3.4 to 4.1 GHz. The core power consumption is 12.9mW. The die area is 0.66mm2.
