The techniques are verified through a number of PLL implementations. Total power consumption is 9 mW and the circuit area including the VCO inductors and on-chip loopfilter is 0. Kostamovaar, Juha University of Oulo. Methods to perform automatic calibration in order to make circuits less sensitive to process variations are proposed.

The strongly non-linear operation of PLL building blocks are analyzed, using both analytical and numerical methods. Noise contributions of various PLL building blocks and their impact on over all system performance are analyzed. All practical PLL implementations suffer from unwanted frequency components such as phasenoise and spurious tones, and since these components affect system performance they must be predicted and minimized.

This thesis discuss the design and implementation of fully integrated PLL circuits. Measured leakage current is less than 2 fA. The circuit use two PLL: The theoretical phase noise is reduced 3. The synthesizer use open-loop direct modulation of the carrier, but unlike conventional implementations, the proposed synthesizer is open both when transmitting and receiving data.

The power consumption is mW in the receive mode and mW in the transmit mode using a 1. A small area amplitude detector circuit is proposed.

A Single Chip A quadrature accuracy of 0.

The total die area is 12mm 2. The design and implementation of a transceiver targeting a dual band IEEE Techniques to reduce impact of interferer down-conversion and noise folding are suggested.

This allows the use of a small area on-chip loop filter without violating noise or spurious requirements. Techniques to predict system performance are investigated.

Thanks to its ability to generate a stable yet programmable output frequency, Phase Locked Loop PLL frequency synthesizers are found in most modern radio transceivers. By using on-chip decoupling gwlam an amplitude control circuit to adjust oscillator bias, the impact of current source noise is eliminated.

The wide-band operation and small input capacitance make the circuit gwlxn for embedding in an RF system on-chip, allowing measurement of on-chip signal levels and automatic calibration. To handle the frequency drift normally associated with open-loop implementations, a low-leakage charge-pump is proposed.

The synthesizer is implemented using a 0. Finally an oscillator topology reducing the phase noise in voltage controlled oscillators is suggested. The transceiver achieves a receiver noise figure of 4. The local oscillators achieve a better than dBc total integrated phase noise.
