A test socket chip for measuring dark currents of infrared (IR) detectors in a focal plane array (FPA) is presented in this paper. A calibration scheme adopted in this chip to cancel the leakage current due to OFF-state MOS switches tied to the measuring path is also demonstrated.
In this paper, a passive 2.45GHz band RFID transponder chip for high data rate communication and with low power consumption has been presented. The passive trans-ponder chip contains five parts: a voltage multiplier converts received RF signal to the DC power supply, a mode selector decides the operating status, a low power dissipation LC-tank voltage… (More)
In this paper, a low parasitic capacitance and low-power CMOS capacitive fingerprint sensor readout circuit is presented. The side effect of parasitic capacitance has been under control with novel layout structure in sensor cell, and minimal size switch is used to reduce non-ideal effects of MOS switch and achieve good linearity. Power dissipation is also… (More)
