Abstract :
The paper presents a low-voltage (≤1 V) exponential function converter and its application to a current mode dB linear variable gain amplifier. The circuit is designed using MOS weak inversion translinear circuits and it is compact and power-efficient. Simulation results demonstrate the effectiveness of the proposed circuit.
