摘要: In this brief, a new low-voltage CMOS circuit to produce current-mode exponential characteristics is proposed. MOSFET transistors in weak-inversion region and translinear principle for the temperature cancellation were used. The functionality of proposed design confirmed with 0.35 μm process technology using ±0.75 V supply voltage. Results demonstrate theoretical analysis verify efficiency structure compared previously reported designs. Around 96 linear-in-dB output current range achieved ±0.5 dB linearity error over normalized input from -5.75 5.75. maximum deviation ±1.27 ±3.35 due 100 °C variations ±10% voltage fluctuation, respectively.
