The CMOS negative impedance converter

Computer-aided design of switched attenuators with high precision

“…1, we will have If we consider expressions (3), (4) as dealing with spectral thermal noise sources in serial branches of &F: e,, e,;.., e,and noise Sources due to the noise produced by the GIC in parallel branches of ALF e,, e4;.-, e,. The ALF noise properties analysis will be carried out by means of continuants [3], [4]. For this purpose, the circuit of fifth-order ALF with the only noise source e4 in the second parallel branch is considered.…”

A CMOS based operational floating current conveyor

“…The input current at the input terminal X is transferred to the output terminal Z (current tracking action) and at the same time there is a voltage following action between the two input ports Y and X, as appeared in Figure 1 [3]. The first two applications using the CCI as a primary block were wideband current measuring device and a negative impedance converter (NIC) [4]. The second-generation current conveyor (CCII) was then presented after the CCI achieved a great success.…”

Wide‐band compact microwave transistor amplifier methodology and the analysis of its input‐matching mechanism using negative impedance converter

“…This study presents design procedures for an amplifier whose gain and resonant frequency are varied by changing the inputmatching type while still maintaining simultaneous conjugate matching at both input and output ports. This design methodology can be effectively utilized for designing matching circuits that incorporate negative impedance converter (NIC) so that the resulting network is able to compensate for impedance variations due to changes in the device point [3,4].…”
