Enhanced wide range tunable CMOS transconductor for signal processing
ABSTRACT: An enhanced wide range current controlled CMOS transconductor is presented. The proposed circuit relies on the behavior of a current controlled current amplifier that uses an unbalanced current mirror. A fifth-order low pass filter based on the enhanced tunable transconductor is also presented as application.KEYWORDS: Transconductor, OTA, tunable trans-conductance, low noise, analog filterRead full text (pdf)
