The adjustable balanced-signal current amplifier presented in this paper amplifies a current by first transforming it into a voltage signal using two poly-silicon resistors and then back into a current signal using a single MOSFET resistor operating in the linear region. We implemented the amplifier in the double-poly 0.6 μm CMOS process by Austria Mikro Systeme International. It consumes 12.4 ...

background: we compared the wave amplitude of visually evoked potential (vep) between patients with esotropic and anisometropic amblyopic eyes and a normal group. methods: the wave amplitude of vep was documented in 2 groups of persons with amblyopia (15 with esotropia and 28 with anisometropia) and 1 group of individuals with normal visual acuity (n, 15). the amplitude of p100 was recorded mon...

We study the amplification of information transfer in excitable systems. We show that excitable systems residing in a steady state near a bifurcation point to complex oscillatory behavior incorporate several frequencies that can be exploited for a resonant amplification of information transfer. In particular, for excitable neurons that reside in a steady state near a bifurcation point to ellipt...
