Manufacturer:STM Description:The OTA, while providing excellent linear amplifier characteristics, does provide a simple means of gain control. For this application the OTA may be considered the realization of the ideal differential amplifier in which the full differential amplifier gm is converted to a single ended output. Because the differential amplifier is ideal, its gm is directly proportional to the operating current of the differential amplifier; in the OTA the maximum output current is equal to the amplifier bias current IABC. Thus, by varying the amplifier bias current, the amplifier gain may be varied: A = gm RL where RL is the output load resistance. Figure 4 shows the basic configuration of the OTA DC gain control circuit. |
