A low-power wide dynamic-range current readout circuit for biosensors

This paper presents an amplifier-less and digital-intensive current-to-digital converter for biosensors. The proposed circuit achieves a first-order noise shaping of the quantization error without any continuous-time feedback circuit. Also, it minimizes ...

This paper presents two new CMOS realization circuits of the pseudo-differential current conveyor (PDCC) in which the second realization is a modified version of the first one. The modified PDCC has a wide dynamic input and output ranges with low ...

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-...
