Abstract-A simple and novel measurement technique to obtain three-port network-parameters of MOS transistors from two-port measurements on a single test structure is presented. The measured data is used in the form of a lookup table (LUT) for RF circuit simulation. It is shown that simulation results obtained with the LUT approach for a 2.4-GHz low-noise amplifier match very well with measurements, thus demonstrating the usefulness of the LUT approach. It is also shown that, for high frequencies, it is important to use the tables of -parameters actually measured rather than those interpolated from low-frequency measurements. This is illustrated with a tuned amplifier simulation example.

“…For the efficient implementation of single-chip transceivers, continuous phase modulation (CPM) using the FM scheme is used to reduce the cost and complexity of transmitters with an I/Q modulation/up-conversion scheme [1], [2]. The I/Q modulation scheme has some disadvantages.…”

“…Furthermore, an additional power amplifier is not necessary when the carrier produced by the RF local oscillator is directly modulated at the desired transmit power level [6]. For these reasons, the CPM scheme is used to implement many lowcomplexity, low-cost, and low-power consumption transmitters, such as Bluetooth [2], [7] and DECT [8], [9]. There has also been an increasing need for both power and spectrum efficient modulation techniques for telemetry systems.…”

Abstract-A continuous phase modulation (CPM) implementation alternative of a recently standardized class of Feher-patented quadrature phase-shift keying (F-QPSK-B) modulation is proposed. Based on the fact that the F-QPSK-B signal has a quasiconstant envelope and continuous phase characteristics, it is shown that it can indeed be generated by the CPM scheme. For example, an F-QPSK-B signal can be fully generated using an existing FM-based transmitter with a modulation index of 0.5.

“…small band, mobile systems. This resulted in some successful designs in both research and commercial environments [5,6,7]. Recent research has shown the possible use of a CMOS upconvertor that combines low power consumption with sufficient power output at frequencies up to 2.4 GHz in a system with data rates already an order of magnitude higher than those of first and second generation wireless devices [8].…”

An upconvertor topology for low power, high bandwidth applications is presented. Using specific circuit techniques and local circuit-level optimization, the power consumption of the total system comprising an on-chip LC-type VCO, a polyphase network quadrature generator, a linear mixer block and an RF-current buffer, has been minimized.A chip has been designed and manufactured in a 0.25µm CMOS technology. The VCO oscillates between 1.68 GHz and 2 GHz. Driven by an external LO, the transmitter operates from 900 MHz up to 2 GHz. At 2 GHz, the upconvertor transmits -12 dBm into 50 Ω with a linearity of more than -35 dBc for base band signals up to 33 MHz.
