Physiological information provided by bio-potential signals is essential and pivotal for
biomedical sensors. As the first stage in the signal chain of the sensor, impedance matching …

Wearable sensors have demonstrated wide applications from medical treatment, health
monitoring to real-time tracking, human-machine interface, smart home, and motion capture …

As a novel approach, two different single-input RTL inverter (NOT gate) circuits using Sziklai
and Darlington pairs are developed and qualitatively analyzed in the present manuscript …

This brief presents a differential difference amplifier (DDA) with a pseudo-differential (PD)
common-mode feedback (CMFB) for neural signal recording. One of the input …

This paper presents a three-channel CMOS integrated current-reuse amplifier, with lateral
bipolar transistors as input stage, designed for the precise measurement of magnetic fields …

Operational amplifiers (op-amps) are widely used in circuit systems. The increasing
complexity of the power supply network has led to the susceptibility of the power supply port …

This letter presents a deadtime offset reduction (DOR) technique to reduce the off-set and
ripple at the output of the capacitively coupled chopper instrumentation amplifier (CCIA) for …

The physiological information transmitted by biological signals is of great importance for the
function of biomedical sensors. In the initial stage of sensor signal acquisition, the …

Local field potentials (LFPs) are the ensemble of low frequency neural signals recorded
invasively via microelectrodes implanted into brain tissues. The LFP signals acquired by …

A split-voltage amplifier architecture is proposed which improves the power efficiency
compared to a conventional implementation. The approach is verified with a prototype …
