Low Power Cmos

A new low power CMOS ASIC for the detection of X-rays was optimized for low power and low noise. Theoretical calculations and optimizations are presented and compared with experimental results. Noise as low as 120+25*Cin [pF] ENC rms was obtained including a silicon detector of 1.3 pF and 0.3nA of leakage. The power consumption is less than 100 W. Other circuit parameters are also shown.

Circuit Configuration

A 320×240 readout circuit (ROIC) for the uncooled pyroelectric infrared detector was fabricated in the double-poly-double-metal (DPDM) N-well CMOS technology. Composed of X- and Y-shift register, column amplifier and correlated double sampling (CDS) circuit, the readout circuit integrated signal from the detector for frame time. It has the pitch of 50um and power dissipation of less than 50 mW. The circuit configuration, operation and testing result are described. Testing result indicates that the designed circuit meets with the requirement. Thermal images were obtained by the hybrid-integrated sensing array.
