Significance: Time-domain functional near-infrared spectroscopy (TD-fNIRS) has been considered as the gold standard of noninvasive optical brain imaging devices. However, due to the high cost, complexity, and large form factor, it has not been as wid

In this letter, we present a CMOS-integrated low noise junction field-effect transistor (JFET) developed in a standard 0.18 $\mu \text{m}$ CMOS process. These JFETs reduce input referred flicker noise power by more than a factor of 10 when compared w
