A 2-GHz Down-Converter with 3-dB Bandwidth of 600 MHz Using LO Signal Suppressing Output Buffer
Summary :
A 2-GHz down-converter for wide-band wireless communication systems is described. To achieve both wide-band output characteristic and LO signal suppression, an on-chip LC series resonator which is resonated at LO signal frequency and a transimpedance amplifier which is used in the output buffer circuit are used. To achieve a low sensitivity to temperature, two kinds of bias circuits; a VT reference current source and a bandgap reference current source are used. The measured 3-dB bandwidth of 600 MHz is achieved. The conversion gain varies less than 0.2 dB within 200 MHz
