The Taylor's series expansion is used for realising the exponential function. In a 0.35μm CMOS process, the HSPICE simulation results show a 15dB linear range with a linearity error of < ±0.5 dB. The total power consumption is < 0.8mW with ±1.5V supply voltage. The circuit can be used in the design of a variable gain amplifier (VGA). © IEE 2000.application/pdf292391 bytesapplication/pdfen-USAmplifiers (electronic); Computer simulation; MOSFET devices; Power converters; Software package HSPICE; Voltage-to-current converters; CMOS integrated circuitsRealisation of exponential V-I converter using composite NMOS transistorsjournal article10.1049/el:20000051http://ntur.lib.ntu.edu.tw/bitstream/246246/200704191001062/1/00830483.pdf
