A low-voltage/low power second order filter that consists of 6 pseudo floating-gate transistors operated in weak inversion is presented, suitable for any kind of application requiring low frequency ranges, such as biomedical products.Abstract:
We present a low-voltage/low power second order filter. The filter consists of 6 pseudo floating-gate transistors operated in weak inversion. The filter is suitable for any kind of application requiring low frequency ranges, such as biomedical products. An electronic cochlea consisting of replicas of the filter is presented. The filter operates at a supply voltage below 1 V, consumes power down to 5 nW, and has a harmonic distortion suppression of -60 dB.read more

Comparison of Quasi-/Pseudo-Floating Gate Techniques and Low-Voltage Applications
Inchang Seo,Robert Fox +1 more
TL;DR: In this paper, the suitability of several quasi-infinite resistors (QIRs) implementations for use in various applications is compared, and a particular QIR implementation is found to minimize dc offset, but requires voltage swings to be limited to less than a diode turn-on voltage.

A low-power wide-dynamic-range analog VLSI cochlea
TL;DR: In this article, an analog electronic cochlea that processes sounds over 6 orders of magnitude in intensity, and that dissipates 0.5 mW is presented, with the wide dynamic range achieved through the use of a wide-linear-range transconductance amplifier, of a low-noise filter topology, of dynamic gain control (AGC) at each cochlear stage, and of an architecture that they refer to as overlapping cascades.
