Due to the limited scenes that synthetic aperture radar(SAR)satellites can detect,the full-track utilization rate is not high.Because of the computing and storage limitation of one satellite,it is difficult to process...
A programmable multi-modulus frequency divider is designed and implemented in a 0. 35μm CMOS process. The multi-modulus frequency divider is a single chip with two dividers in series,which are divided by 4 or 5 presc...
Pulse width modulation ( PWM) drive control digitalization is the key for the full digital invert power supply. New ideas are proposed, which are based on field programmable gate array ( FPGA ). First, digital PWM...
