Book Description
A voltage-controlled oscillator (VCO) is one of the most important basic building blocks for analog and digital circuits. There are different implementations of VCOs. One of them is the ring oscillator based VCO. A ring oscillator based Temperature Sensors designed is sensitive for small variations of temperature. The Temperature is linearly dependent on the oscillation frequency of ring oscillator, as a way of converting temperature to a digital read out. The proposed temperature sensors occupies smaller silicon area with higher resolution than the conventional temperature sensors based on band gap reference. It was designed to achieve better than 1 DEGREESo C of temperature resolution, which is suitable for almost any application of an integrated CMOS temperature sensor. Special attention has been given to the integration of design of two different Ring Oscillators in order to achieve lower voltage operation when the design is implemented in an advanced CMOS p

Book Description
This guide emphasizes jitter for time domain applications so that there is not a need to translate from frequency domain. This provides a more direct path to the results for designing in an application area where performance is specified in the time domain. The book includes classification of oscillator types and an exhaustive guide to existing research literature. It also includes classification of measurement techniques to help designers understand how the eventual performance of circuit design is verified.

Book Description
A voltage controlled ring oscillator plays very important role in high speed systems due to its easy integration capability. The analysis of different VCOs and their applications are discussed and analyzed in this book. There are number of applications of ring VCOs, one of the most important application is phase locked loop. The main task of the PLL is to maintain the coherence between output signal and reference signal by phase comparison. The proposed PLL using improved performance voltage controlled ring oscillator shows better performance in terms of frequency range and power consumption.

Book Description
In the tremendous growth of wireless handheld devices, low power consumption becomes a major consideration in radio frequency integrated circuit (RFIC) designs. This book introduces a multistage voltage controlled ring oscillator. The proposed structure uses 45 nm CMOS Technology in cadence. PSS analyses are performed in order to determine the frequency of oscillation and the influence of parameters such as supply voltage, temperature or load capacitance over the oscillation frequency. A transient analysis is performed to illustrate the effects of the parasitic parameters over the oscillation frequency. Ring oscillators with different number of stages like 7, 9 and 11 were designed successfully and their performance parameters are discussed in great detail and compared to reach to solutions to the challenges faced by the current Ring Oscillator technology. The challenges are phase noise, frequency jitter, period jitter, delay, jitter, total harmonic distortion (THD), transfer function etc. and are dealt appropriately in the system designs proposed for different number of stages. For example, a certain signal may have a phase noise of -80 dBc/Hz at an offset of 10 KHz.

Book Description
This book describes an alternative method of realizing accurate on-chip frequency references in standard CMOS processes. This method exploits the thermal-diffusivity of silicon, i.e. the rate at which heat diffuses through a silicon substrate. This is the first book describing the design of such electrothermal frequency references. It includes the necessary theory, supported by practical realizations that achieve inaccuracies as low as 0.1% and thus demonstrate the feasibility of this approach. The book also includes several circuit and system-level solutions to the precision circuit design challenges encountered during the design of such frequency references.

Book Description
This book discusses new techniques for detecting, controlling, and exploiting the impacts of temperature variations on nanoscale circuits and systems. A new sensor system is described that can determine the temperature dependence as well as the operating temperature to improve system reliability. A new method is presented to control a circuit’s temperature dependence by individually tuning pull-up and pull-down networks to their temperature-insensitive operating points. This method extends the range of supply voltages that can be made temperature-insensitive, achieving insensitivity at nominal voltage for the first time.
