Abstract
A wide dynamic range Operational Transconductance Amplifier (OTA) (100) includes a differential voltage to current converter (206) for converting an input voltage to a current level. A pair of programmable folded cascodes (201) are coupled to the output of the converter (206) in order to render the amplifier (100) programmable. Current sources (222 and 226) are employed to provide output sourcing current. There is also included a common mode feedback (106) for maintaining the output signal substantially and equally centered between rails of the operating voltage (208).
