Abstract :
Current-voltage (I-V) and voltage-current (V-I) converters for use in current-mode analog integrated circuits are described. The proposed I-V converter has 2.4 decades of linear range, a THD of 0.82% and a bandwidth of 10 MHz. The V-I converter exhibits 5 decades of linear range with a 30 MHz bandwidth at a 1muA bias current and introduces no additional non-linearities. Both circuits have been implemented in a 0.5mum standard digital CMOS process
