Abstract
This paper describes a RF front-end for DVB-SH (2.17-2.2 GHz) implemented in UMC CMOS 90 nm process. This
receiver includes a Low Noise Amplifier (LNA), a Single-to-Differential Converter and a Mixer. The LNA is based on
cascode topology combined with a narrow band impedance matching and LC tank load. The Single-to-Differential
Converter generates a pair of differential output signals from a single input, which have balanced amplitude and
phase. This converter is followed by a Gilbert Cell based quadrature mixer. Post-layout simulations show a
conversion gain of 33.3-32.7 dB, a 2.2 dB of noise figure, an input return loss (S11) of -15 dB and an output
compression point of 0.3 dBm. This combination draws 21.78 mW from a 1.2 V supply.

Conclusions
A Fully Integrated RF Front-End for DVB-SH was
implemented in UMC CMOS 90 nm process. This receiver
includes a LNA, a Single-to-Differential Converter and a
Mixer. The LNA is based on cascode topology combined
with a narrow band impedance matching and LC tank load.
The Single-to-Differential Converter generates a pair of
