Abstract:
This article presents a high-resolution, wide dynamic-range (DR) current-to-digital converter (IDC) capable of directly digitizing a broad range of bio-current signals. To achieve high resolution, the IDC uses a second-order continuous-time delta–sigma modulator (CT-DSM) architecture with a low-noise current-recycling operational amplifier (op-amp) and a highly linear pseudo-differential voltage-controlled oscillator (…
