摘要: This study presents an inverter-based inductorless single-to-differential (S2D) wideband low-noise amplifier (LNA). The proposed LNA has three inverter-based gain stages with a global shunt feedback resistor for wideband input impedance matching. Moreover, a shunt capacitor with a current bias transistor in the third gain stage enhances the gain/phase imbalances and the linearity of the pseudo-differential outputs. When implemented in a TSMC 0.18- μm CMOS process, this wideband LNA covering DC-1.4 GHz achieves a S21 of 16.4 dB, a minimal input third-order intercept point (IIP3) of -13.3 dBm, and a minimal noise figure (with output buffers) of 3 dB. The output gain and phase imbalances are less than 1 dB and 2.5°, respectively, within 1 GHz. The chip consumes 12.8 mW from a 1.8 V supply. 其他題名: LMWC 出版者: IEEE 出版日期: 2014-07 出處: IEEE microwave and wireless components letters, 2014-07, Vol.24 (7), p.472-474 資源來源: IEEE Electronic Library (IEL) 識別號: ISSN: 1531-1309 識別號: EISSN: 1558-1764 識別號: DOI: 10.1109/LMWC.2014.2316495 識別號: CODEN: IMWCBJ
