Overall Topologies and Frequency Compensation
1996An operational amplifier intended for use in VLSI mixed-mode systems should be able to operate under conditions which differ from application to application. One can think of different types of passive feedback, varying load impedances, process variations, temperature variations, and many more.

A High-Frequency Phase-Compensation Fractional–N Frequency Synthesizer
2005 IEEE International Symposium on Circuits and Systems, 2005A new type of high-frequency fractional-N frequency divider with a phase compensation technique is developed, which can operate for frequencies ranging from 1 GHz to 2.5 GHz, and achieve a divide ratio of (256-271) + (f/16). The on-chip phase compensation by a delay-locked loop (DLL) is adopted to reduce the fractional spurs in the fractional-N ...

Bias compensation in flood frequency analysis
Hydrological Sciences Journal, 2015AbstractFlood frequency analysis (FFA) is essential for water resources management. Long flow records improve the precision of estimated quantiles; however, in some cases, sample size in one location is not sufficient to achieve a reliable estimate of the statistical parameters and thus, regional FFA is commonly used to decrease the uncertainty in the ...

Temperature compensation of dielectric resonator frequency
2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004A new way for the thermal compensation of dielectric resonators (DR) is proposed for the DR made of high-quality, but not thermally stable, materials. Thermal stability can be achieved for such DRs in the case when the DR is cut into two parts with a small air slot between them. High Q factor is preserved, as well as a small-sized design.

Compensator design using the frequency - domain approach
SIMULATION, 1979This paper presents an analytical technique for com pensating a system in the frequency domain to meet phase margin and static-error coefficient require ments at a specified gain-crossover frequency. The paper describes a BASIC program that implements the techniaue.

High-Frequency Compensation of RC Amplifiers
Proceedings of the IRE, 1954The high-frequency compensation of single- and multistage resistance-coupled amplifiers is discussed with special reference to the transient response. Optimum parameters are given for a number of typical cases. It is shown that, for the simplest type of high-frequency compensation with one coil in the anode lead, staggering of the time constants in a ...

Frequency Independent IQ Imbalance Estimation and Compensation
2013For narrow band systems, the IQ imbalance can be assumed to be frequency independent. In this chapter, we look at the frequency independent IQ imbalance estimation and compensation. We start from simple RX only IQ imbalance estimation and compensation, then discuss joint TX and RX IQ imbalance compensation and estimation.

On analytical frequency domain compensator design
Proceedings of 1994 33rd IEEE Conference on Decision and Control, 2002An analytical design procedure for forward path servo loop compensation is discussed, applicable to both continuous and discrete time systems. Compensator design criteria include the following error, phase margin, parameter sensitivity, and disturbance rejection. The algorithm can be implemented in a PID controller configuration. >

Basic Frequency Compensation of Integrated Circuits
1995Monolithic IC technology puts severe limitations on the options available for frequency compensation. A major restriction is the fact that inductors of any significant value cannot be integrated, while these components play an important role in the conventional compensation practice.

Frequency Offset Compensation in OFDM Transmission
2018Orthogonal Frequency Division Multiplexing (OFDM) has been a signature technology in today’s wireless communications such as Long Term Evolution (LTE) and Wireless Local Area Network (WLAN). With its high spectral efficiency, robustness in multipath environment, flexible allocation in subcarriers and other merits, OFDM provides higher transmission ...
