摘要
Disclosed is an operational transconductance amplifier (OTA) for an ultra-wideband (UWB) filter which is a core block enabling processing of UWB signals among RF blocks constituting a coherent UWB receiver corresponding with IEEE 802.15.4a UWB standards. A Nauta-operational transconductance amplifier for the UWB filter in a UWB based indoor positioning system, according to the present invention comprises: two first g_m cells which receive an input positive voltage and an input negative voltage, respectively; and two second g_m cells, each of which has an input terminal connected to an output terminal of any one among the first g_m cells and an output terminal connected to an output terminal of the other among the first g_m cells. The Nauta-operational transconductance amplifier for the UWB filter outputs a first output current and a second output current having a current difference proportional to a voltage difference between the input positive voltage and the input negative voltage.;COPYRIGHT KIPO 2014
