In this paper, we design a successive approximation register (SAR) analog-to-digital converter (ADC) suitable for multimode radar transceivers. For multimode radars, the sampling rate required by ADC varies according to the continuous wave (CW) or fr

In this paper, an energy-efficient switching scheme with additional quarter-reference voltage sources in a successive approximation register (SAR) analog-to-digital converter (ADC) is proposed for a low power and small area device for frequency modul

In this work, a multi-mode radar transceiver supporting pulse, FMCW and CW modes was designed as an integrated circuit. The radars mainly detect the targets move by using the Doppler frequency which is significantly affected by flicker noise of the r

In this paper, we investigate some generalized results of applications of fractional integral and derivative operators to a subclass of analytic functions for operators on Hilbert space.

In this paper, we design a balun that operates at 60GHz. The proposed balun is based on a substrate integrated waveguide (SIW) structure that can reduce losses in high frequency bands. A single-ended signal is divided by 3-dB power divider, and then
