This paper presents a 2V, full CMOS transmitter circuit to be included in a DCS-1800 wireless system. The paper discusses the design plan of the transmitter including the optimized interface with the differential oscillator, the poly-phase filter, the mixers and the preamplifying output driver. Traditional inter-building block buffers have been questioned, resulting in a transistor level optimization of the total transmit path as one building block. The measurements show that the DCS-1800… CONTINUE READING
