“…As shown in the figure, gain control is applied in both the LNA and the variable gain amplifiers (VGAs). Here, an LNA with two gain modes is assumed [19]- [21]. This type of LNA has been discussed in [19] and [22].…”

“…Here, an LNA with two gain modes is assumed [19]- [21]. This type of LNA has been discussed in [19] and [22]. The VGAs at baseband compensate the rest of the required gain.…”

“…• A double-balanced mixer is adopted for a QDEM as an alternative architecture to the active harmonic mixer, which was introduced in the previous work [2]. The LO buffer employs capacitor degeneration in order to suppress the DC offset injection to the mixer, which causes local leakage, without an active DC offset canceler.…”

“…Therefore, a reduction in DC offset transition for the gain change is also required for mobile communication terminals. We have previously reported a fully differential direct conversion receiver, which reduced DC offset including time variation [2]. In [2], we reported that DC offset variation is sufficiently suppressed and causes negligible degradation in receiver performance.…”
