This paper presents a low-power, small-size, wide tuning-range, and low supply voltage CMOS current-controlled oscillator (CCO) for current converter applications. The proposed oscillator is designed and fabricated in a standard 180-nm, single-poly, six-metal CMOS technology. Experimental results show that the oscillation frequency of the CCO is tunable from 30Hz to 970MHz by adjusting the control current in the range of 100fA to 10µA, giving an overall dynamic range of over 160dB. The operation of the circuit is nearly independent of the power supply voltage and the circuit operates at supply voltages as low as 800mV. Also, at this voltage, with control currents in the range of sub-nano-amperes, the power consumption is about 30nW. These features are promising in sensory and biomedical applications. The chip area is only 8.8×11.5µm2. |
