A low voltage wide dynamic range CMOS active pixel sensor (APS) using 0.18 mum standard CMOS process is presented. The dynamic range of the proposed APS is 42 dB and it is twelve times more than a conventional CMOS APS architecture. The power consumption of the APS is 86 nW at 1 V supply. The fill factor is about 40% with 11 mum times 11 mum pixel size.
A low power consumption CMOS complementary cross-coupled LC-tank voltage-controlled oscillator (VCO) is presented. The low power consumption VCO has been implemented with tsmc 0.18 mum 1P6M CMOS technology. A pseudo-resistance transistor is utilized to reduce the DC bias current under a fixed supply voltage. The circuit consumes 2.58 mA from a 1.6 V power supply which saves up to 27% power compared...
