Several kinds of biasing circuits for high linearity driver are analyzed and compared using Volterra series analysis. Theoretical analysis and nonlinear simulation of a one-stage RFIC amplifier indicate about 10 dB dependence of the IP3 parameter on the biasing scheme being used. Based upon the analysis, transistor current source with inductor is used for(More)
We suggest the new monolithic, tunable, recursive filters having variable, uniform, and high gain. We change the location of amplifier to achieve higher gain. We use the cascode amplifier as VGA to get the variable, uniform and high gain. To achieve higher Q and low power consumption, we also fabricate the second-order filter using only one amplifier. The(More)
