The design of a low-power-integrated potentiostat that measures electric current intended for a Chagas disease detection application is presented. This circuit can generate and measure currents from 1 to 10 μA with a relative error under 5%. The remaining part of the circuit consumes only 1.5 μA. The circuit was designed using the 0.6 μm XC06 technology from the X-FAB, with a total silicon area of 0.24 mm 2 (without pads).

“…Another well known continuous time amperometric readout technique is based on current mirror amplifiers [129,130,134,[136][137][138][139], such as those shown in Figure 12. A closer look at the configurations in Figure 10 reveals that the potentiostatic control amplifier A 1 provides the current to the sensor, so it can be copied and eventually amplified by simple current mirror configurations.…”

Smart wearables, among immediate future IoT devices, are creating a huge and fast growing market that will encompass all of the next decade by merging the user with the Cloud in a easy and natural way. Biological fluids, such as sweat, tears, saliva and urine offer the possibility to access molecular-level dynamics of the body in a non-invasive way and in real time, disclosing a wide range of applications: from sports tracking to military enhancement, from healthcare to safety at work, from body hacking to augmented social interactions. The term Internet of Wearables (IoW) is coined here to describe IoT devices composed by flexible smart transducers conformed around the human body and able to communicate wirelessly. In addition the biochemical transducer, an IoW-ready sensor must include a paired electronic interface, which should implement specific stimulation/acquisition cycles while being extremely compact and drain power in the microwatts range. Development of an effective readout interface is a key element for the success of an IoW device and application. This review focuses on the latest efforts in the field of Complementary Metal–Oxide–Semiconductor (CMOS) interfaces for electrochemical sensors, and analyses them under the light of the challenges of the IoW: cost, portability, integrability and connectivity.

“…A potentiostat has the function of current-to-voltage conversion for a single channel. However, for pA-level current measurements, the conventional solutions suffered from insufficient accuracy [24,25,26] or limited dynamic range [27,28]. Besides, it is necessary to consider the performance differences between the single channel and the readout array.…”

Nanopore-based DNA sequencing technology features the advantages of label-free, low-cost, and rapid detection. However, the existing nanopore sequencing readout cell or array for the lower area and power consumption become prohibitive. This brief presents a low noise potentiostat readout array. Based on the five-transistor OPA, the half-shared amplifier reduces the area and power consumption of the cell by about 50%, and shows a good suppression effect on mid-to-high frequency noise in the output channel. As a result, high-throughput is achieved with low noise. The performance of the proposed array channel has been evaluated in 180-nm CMOS process, the inputreferred current transient noise was 2.28 pARMS, the power consumption was 2.2 µW and the unit area was 10×12 µm 2 .
