Abstract:

A closed-loop self-excitation/detection application specific integrated-circuit (ASIC) based on the phase-locked loop (PLL) used for micro-resonant infrared detector is designed to improve the measurement accuracy, miniaturization and integration. A switched capacitor array is proposed and used in the VCO to meet the requirements of the system. The VCO was implemented by 0.18 μm CMOS technology, the chip area is 1.1*0.9 mm2. The proposed VCO can be operated at 2.603.38 GHz, the measured phase noise are -125.9 dBc/Hz@1MHz at 2.60 GHz and -123.3 dBc/Hz@1MHz at 3.38GHz respectively. The VCO draws 3.06 mW power consumption from a 1.8 V supply.
