Abstract:
The present invention relates to a novel and inventive compound device structure for a low noise current amplifier or trans-impedance amplifier. The trans-impedance amplifier includes an amplifier portion, which converts current input into voltage using a complimentary pair of novel n-type and p-type current field-effect transistors (NiFET and PiFET) and a bias generation portion using another complimentary pair of NiFET and PiFET. Trans-impedance of NiFET and PiFET and its gain may be configured and programmed by a ratio of width (W) over length (L) of source channel over the width (W) over length (L) of drain channel (W/L of source channel/W/L of drain channel).

Claim (Index 13):
An wireless signal transceiver, comprising:\n a. a wireless antenna; b. a differential current amplifier, comprising a first, second and third complementary pairs of a n-type current field-effect transistor (NiFET) and a p-type current field-effect transistor (PiFET); wherein each of said NiFETs and PiFETs comprises:\n a source terminal, a drain terminal, a gate terminal, and a diffusion terminal of a corresponding conductivity type of said each of said PiFET and NiFET, defining a source channel between said source terminal and said diffusion terminal, and a drain channel between said drain terminal and said diffusion terminal, said diffusion terminal causes changes in said diffused charge density throughout said source and drain channels, and said gate terminal is capacitively coupled to said source channel and said drain channel; \n said gate terminal of said PiFET and said gate terminal of said NiFET are connected together to form a common gate terminal, said source terminal of said NiFET is connected to negative power supply and said source terminal of said PiFET is connected to positive power supply, and drain terminals of said NiFET and said PiFET are connected together to form an output; \n said common gate of said first complimentary pair and said common gate of said second complementary pair are connected with said output of said second complementary pair, and received by said common gate terminal of said third complementary pair; \n said diffusion terminal of said PiFET of said first complementary pair receives said antenna; \n said diffusion terminal of said PiFET of said third complementary pair is resistively coupled with said antenna; \n said diffusion terminals of said NiFET of said first, second and third complementary pairs are connected together to receive current for gain control; \n said output of said first complementary pair forms a voltage output, said output of said second complementary pair provides an analog ground for said voltage output, and said output of said third complementary pair provides an bias voltage for said voltage output.
