This open-loop gain enhancement circuit in 1.2pm CMOS does not require cascode or long-channel transistors, thus maximizing output swing and input common-mode range [1,21. Since gain enhancement is achieved not by increasing output resistance, but by matching main and replica amplifiers, high effective open-loop gain is maintained even with resistive loads. This circuit can be used with any tra...

The possibility of using non-Foster circuit to expand the bandwidth of a monopole antenna is investigated theoretically. Beginning with an inductor-loaded monopole antenna resonating at different frequencies by changing the value of the loaded inductor, we show that a frequency-dependent inductor is needed to enhance the bandwidth of the monopole antenna. The curve for the reactance of the freq...

A piezoelectric/magnetostrictive composite vibrating energy generator is introduced, and its output characteristic is analyzed. In order to increase the maximum output power of the vibrating energy harvester, a new up-conversion matching circuit is proposed, which can change the low frequency vibrating signal into a narrow bandwidth signal focused on a higher frequency. The matching circuit wit...

An integral challenge in automated synthetic circuit design is to select the optimal set of parts to populate an abstract circuit topology, so that the circuit behavior best approximates the desired one. In some cases, it is also possible to reuse multi-part constructs, or modules that have been already built and experimentally characterized. Efficient part and module matching algorithms are es...

Fuzzy theory is widely studied and applied. This article introduces an adaptive control scheme for a class of non-linear systems with Markov jump switching. The introduced supposes that the system submitted to external disturbances under imperfect premise matching. By using discrete-time Takagi–Sugeno fuzzy models, sliding mode observer-based utilized estimate unmeasured states system. We build...

A highly efficient class E power amplifier is demonstrated for application to wireless power transfer system. The amplifier is designed with an L-type matching at the output for harmonic rejection and output matching. The power loss and the effect of each component in the amplifier with the matching circuit are analyzed with the current ratio transmitted to the output load. Inductors with a qua...
