This paper presents the experimental results of two different techniques, the already known inductive degeneration technique and the new capacitive filtering technique, for reducing the phase noise in RF CMOS VCO's. The techniques are applied to two distinct VCO designs, showing that the largest phase noise reduction (up to 7 dB at 3 MHz offset frequency from the carrier) is achieved via inductive

This paper addresses the inverse problem of reconstructing a medium’s instantaneous, nonlinear response to electromagnetic excitation. Using reflection and transmission data for an almost arbitrary incident field on a homogeneous slab, we are able to obtain the nonlinear constitutive relations for both electric and magnetic fields, with virtually no assumptions made on the specific form of the rel

Regional cerebral blood flow (rCBF) measurements and clinical ratings were performed on 17 schizophrenic patients and a subgroup of 10 medication-free patients before and after treatment. While clinically exacerbated patients had normal blood flow, patients in remission showed a redistribution of flow with lower values in frontal areas. Anteroposterior ratios correlated with the degree of behavior

Value selling is often presented to be the most profitable and competitive sales practice in business markets. This paper argues that the relevant theory does not consider the consequences of introducing value selling for the relationship between the individual salesperson and buyer. This is problematic since the literature assigns most responsibilities within value selling to the salesperson. The

Focusing new teacher students has at least two different implications. The students are new in the meaning of being first term students. Analyses of the recruitment to teacher education show that the new students have other social characteristics than before. During the last two decades fewer students from academic families and fewer students with high degrees from upper secondary school have ent
