Second-harmonic control is implemented in a balanced common-emitter configuration to facilitate frequency-independent third-order intermodulation distortion cancellation. Moreover, this circuit configuration facilitates a simultaneous match for either power and linearity or noise and linearity. Experiments demonstrated an improvement of over 15 dB in the output third-order intercept point while...

The paper presents project of reprogrammable chip – FPGA, designed with current-mode gates novel digital gates operating with constant, continuous power supply current. Such continuous supply is a perfect one for analog-digital circuits, which are located on the same single die. Switching of digital part of the chip don’t disturb analog part. Based on the proposed approaches to minimizing logic...

An electronically tunable voltage-mode universal biquadratic filter with one input and five output terminals employing differential difference current conveyor transconductance amplifiers (DDCCTAs) has been proposed. The proposed circuit uses only two DDCCTAs, two grounded resistors and two grounded capacitors. It can realize all the five standard biquadratic filter functions, namely lowpass, b...

The effect of MOSFET gate-oxide reliability on MOS switch with bootstrapped technique is investigated with the switched-capacitor circuit in a 130-nm CMOS process. The sample-and-hold amplifier with the openloop configuration is used to verify the impact of MOS switch gate-oxide reliability on the switched-capacitor circuit. After overstress on the MOS switch of sampleand-hold amplifier, the ci...

In this paper, new simple circuit models for developed SiC pin diodes are proposed. They are based on the electrical characteristics obtained in experiments without any detail information of internal structure and physical parameters. The validity of the circuit models is confirmed by correspondence between simulated characteristics and experimental one. The model installed in the experimental ...

In this paper we present an electronic circuit for position or capacitance estimation of MEMS electrostatic actuators based on a switched capacitor technique. The circuit uses a capacitive divider configuration composed by a fixed capacitor and the variable capacitance of the electrostatic actuator for generating a signal that is a function of the input voltage and capacitive ratio.

The new phase-shifter configuration described in this report uses a negative group delay (NGD) active circuit. In this topology, a classical transmission line is set in cascade with an NGD circuit whose phase slopes are alike, but opposite, to get a constant and broadband phase shift. The proposed approach was validated through the design and measurement of a phase shifter, which exhibited a co...
