Abstract :
The dynamic range performance of an active MOS attenuator circuit suitable for analog monolithic applications is presented. The attenuator exhibits low input referred noise. An application using the active attenuator as the input stage of a transconductance amplifier is discussed. Tradeoffs between power consumption, circuit area, attenuation ratio and dynamic range are considered
