In the past few years, a tremendous advancement in the outcome of biomedical circuits and systems has been reported. Unfortunately, at the time of the sudden outbreak of COVID-19, the electronic engineering researchers felt dearth on their side to combat the pandemic, as no such immediate cutting-edge solutions were ready to recognize the virus with some standard and smart electronic devices. Likely, in this paper, a detailed comparative and comprehensive study on circuit architectures of the biomedical devices is presented. Mostly, this study relates the industry standard circuit schemes applicable in non-invasive health monitoring to combat respiratory illnesses. The trending circuit architectural schemes casted-off to tapeout non-invasive health-care devices available in the past literature are meticulously and broadly discussed in this study. Further, the comprehensive comparison of the state of art of the device performance in terms of supply voltage, chip area, sensitivity, dynamic range, etc. is also shown in this paper. The inclusive design processes of the health monitoring devices from Lab to Industry is thoroughly discussed for the readers. The authors think, that this critical review summarising all the trending and most cited health-care devices in a single paper will alternately help the industrialists to adapt and modify the circuit architectures of the health monitoring devices more precisely and straightforwardly. Finally, the demand for health monitoring devices particularly responsible to detect respiratory illnesses, measuring blood pressure and heart-rate is growing widely in the market after the the incident of COVID-19 and other respiratory diseases.

“…1, for the photodiode, such that the current in this element, IPD, is mainly due to the amount of light it receives. The design presented in [19] (also based on using a TIA followed by an ADC) is particularly worthy of note, as here, the LEDs are replaced by silicon nanowires, while several modifications are introduced in the circuit to reduce reading errors. The circuits are complex for all of these designs since, together with the ADC, several operational amplifiers (OAs) and discrete elements are needed for implementation.…”

“…The sigma-delta analog-to-digital converters (ADCs) have been used in many applications, such as audio systems, smart temperature sensors and readout integrated circuits (ROIC) [1,2,3,4,5,6,7,8]. Such applications often process low level signals with low frequencies, which are easily affected by DC offset and 1/f noise when converting to digital domain.…”

This Letter presents a low-residual-offset second-order sigma-delta modulator. By inserting a chopper working at low frequency to the mirrored integrator at the first stage of the modulator, the original residual offset is transferred to a high frequency, which can be removed by the filter. Besides, by applying the second-order fractal sequence as the timing of the new added chopper, the residual offset accumulation problem due to the integration at the second stage can be avoided. To evaluate the effect of residual offset suppression conveniently, a programmable timing is integrated to the design to control the state of the added chopper. The presented modulator is fabricated in a 0.18 um CMOS technology, the core area of which is 0.38 mm 2 . Based on the measurement results, the DC offset of the sigma-delta modulator with the proposed method is reduced by 85.6 μV. The modulator realizes 64.8 dB dynamic range with 1 MHz sampling rate, which consumes 0.96 mW from a 3.3 V supply.
