  • Abstract
    In this paper, a new current amplifier with a very simple structure is proposed. The most significant features of this circuit are as follows: (1) It can accept very weak input currents in a pA-nA range. (2) The mid-band current gain is about 60 dB. (3) The gain-bandwidth product can reach as high as 300 MHz. (4) The power dissipation is around 0.5 mW. The new circuit has been implemented using a CMOS digital technology and has been tested to validate the circuit specifications.
