This paper presents a 5-GS/s 12-way 10-b time-interleaved successive approximation register (SAR) ADC for direct sampling receivers. Proper signal and clock distribution along the multiple channels are utilized to mitigate interchannel bandwidth and timing mismatches. A digitally assisted calibration is introduced to remove the interchannel offset, gain, and timing mismatch. The T-type bootstrapped...
A highly linear, 3rd order, active-RC low-pass elliptic filter with Variable Gain Amplifier (VGA) is presented. The new derivative-free biquad topology for an elliptic filter could be easily extended to a higher order filter using a cascade of biquads and it will have a zero capacitive spread when used along with a VGA. It is introduced to minimize the power consumption of an active-RC filter in a...
In this paper, a wide-band patch antenna that works in S band is designed, which using E-shaped patch antenna. By using the microstrip antenna design technology, the requirement of a certain type of wireless equipment is gotten. In order to broaden the bandwidth of the antenna, E-shaped patch antenna is used to design, and the determination for grooving of type E patch size method has been discussed...
