A wideband balun–LNA

An Inductor-less Sub-mW Low Noise Amplifier for Wireless Sensor Network Applications

“…12. Table 2 presents postlayout simulation results of the proposed shunt feedback CG-LNA and the recently published LNAs [20][21][22]. The simulation results are displayed in 2.4 GHz ISM band.…”

Design of a reconfigurable front‐end for a multistandard receiver for the frequency range of 800 MHz to 2.5 GHz

“…The design of LNTA is based on Fatin and Fatin 22 and was thoroughly explained there. The value of R 1 is set based on the voltage drops across the devices.…”

“…The value of R 1 is set based on the voltage drops across the devices. The design of LNTA is based on Fatin and Fatin 22 and was thoroughly explained there. The value of g m2 (transconductance of the M2) depends on the R F resistor value.…”

“…The proposed LNA is shown in Figure 5. This LNA is a common source amplifier with active feedback, which was introduced in Borremans et al, 21 but later has been modified 22 to perform the balun function as well. This block has been extensively discussed in Fatin and Fatin.…”

“…This block has been extensively discussed in Fatin and Fatin. 22 In the proposed receiver, this circuit is utilized as an LNTA to be able to drive the subsequent stage that is a passive mixer designed to operate in current mode and is explained in the following section.…”
