A 2.4 GHz CMOS transceiver for Bluetooth

MOS varactors with n- and p-type gates and their influence on an LC-VCO in digital CMOS

“…Values for the capacitance and quality factor of the varactors are retrieved by (1) with the series resistance of the varactor. The inductor features an inductance of 4.5 nH and a dc series resistance of 4.7 .…”

“…T HE design of single-chip transceivers has already been demonstrated in low-cost CMOS technologies [1]- [11] and industrial solutions are already available [12]. Among the key elements of the important transceivers for wireless communications are voltage-controlled oscillators (VCOs).…”

17 Interface Circuitry and Microsystems

“…[126] Table 17.13 summarizes the most important features of the Bluetooth interface. Several fully integrated Bluetooth transceivers are available on the market, either as commercial parts or as IP blocks [127][128][129][130] to be included in custom integrated circuits, thereby allowing the wireless connection feature to be included in microsystems or micromodules without considerable design effort.…”

A Transformer-Matched Millimeter-Wave CMOS Power Amplifier

“…The CMOS single-chip transceivers have been widely implemented at RF and microwave frequencies for low cost and high reliability [1,2]. As the gate width scales down deeply, the single-chip solution becomes feasible even at millimeter-wave (mm-wave) frequencies [3,4].…”
