Abstract

A track- and hold-circuit has been designed, which can function as a subsampling mixer in the front-end of a receiver in a wireless communication handset. In a 0.6 μm CMOS-technology, two test chips have been made, one with the stand-alone mixer and one with an A/D converter integrated on the same chip. Measurement results show that the mixer is able to handle an input signal with a frequency of 1.8 GHz. The circuits operate with a single 5 V supply
