—A multiband flexible RF-sampling receiver aimed at software-defined radio is presented. The wideband RF sampling function is enabled by a recently proposed discrete-time mixing downconverter. This work exploits a voltage-sensing LNA preceded by a tunable LC pre-filter with one external coil to demonstrate an RF-sampling receiver with low noise figure (NF)(More)
A variety of genetic alterations are considered hallmarks of cancer development and progression. The Ikaros gene family, encoding for key transcription factors in hematopoietic development, provides several examples as genetic defects in these genes are associated with the development of different types of leukemia. However, the complex patterns of(More)
A low noise variable gain amplifier (LNVGA) is fully designed for operation over a wideband. Since a low noise figure (NF) and a high 1 dB compression point (P1dB), i.e. large dynamic range, is difficult to achieve in CMOS technology, gain controllability is exploited to increase the overall system dynamic range. The LNVGA is composed by a low noise(More)
