چکیده
This paper proposes a CMOS low-power low-voltage microphone preamplifier for a cochlear implant system. The proposed preamplifier using the Flipped Voltage Follower Current Sensing (FVFCS) technique to achieve low voltage, low power consumption. The proposed circuit was designed and simulated using a 0.35 m CMOS process. Simulation results showed that the preamplifier can achieve 22-dB voltage gain while dissipating only 5.2 W from 1.4-V power supply voltage.

Micropower Analogue Building Blocks for Template Matching in Implantable Devices
The design of analogue low power VLSI building block is very important for implantable devices, like cochlear implants and implantable cardioverter deebril-lators(ICD). In this paper we describe the micropower analogue building blocks for implementing the template matcher used for intracardiac electrogram (ICEG) clas-siication and data compression in an ICD. These blocks were fabricated using O...
متن کاملDynamic-range analysis and maximization of micropower G[subscript m]-C bandpass filters by adaptive biasing
We analyze and present an input gain-varying scheme for maximizing dynamic range in a well-known Gm–C bandpass filter by both minimizing noise for small input signals, and by achieving balanced swing levels at all filter nodes for large input signals. A micropower bandpass filter suitable for use in cochlear implants and other powerconstrained biomedical applications was implemented and tested ...

We have designed a process-insensitive preamplifier for an optical receiver, fabricated it in several different minimum feature sizes of standard digital CMOS, and demonstrated design scaleability of this analog integrated circuit design. The same amplifier was fabricated in a 1.2 μm and two different 0.8 μm processes through the MOSIS foundry [1]. The amplifier uses a multistage, low-gain-per-...
متن کاملCOCHLEAR IMPLANTATION IN IRAN
Cochlear implantation has become an increasingly common procedure in the rehabilitation of selected cases of profound deafness.' Patients should have profound total bilateral sensorineural hearing loss. Sound is transformed into small electric currents which stimulate the auditory nerves in the cochlea and generate the hearing sensation. The nucleus cochlear implant is the result of more t...
