Abstract
A new CMOS electronically tunable second-generation current conveyor ( ECCII ) with wide tuning range was presented. By introducing the log-antilog current amplifier based on DDCC,the current gain was controlled elec-tronically by adjusting the ratio of DC bias currents of the ECCII,In a certain range of the bias current,0<k≤10. The input stage adopts rail to rail structure by adding a cascode current mirror in the second level,increase the volt-age tracking accuracy. Using SMIC 0.18μm CMOS technology,the Spectre simulation results showed that vx/vy and iz/ix had -3 dB bandwidth of 300 MHz and 155 MHz,Voltage tracking accuracy is 0.997,DC power consumption was 1.642 4 mW. The ECCII has comprehensive applications in the tunable current mode continuous time filters.关键词
