- They are vref , iref , current matrix , switch matrix , latch and decoder . vref , current matrix , switch matrix and decoder are the key parts in dac design . the errors caused by them are analyzed and suppressed in the paper
其中,基准电压电路,电流源阵列、开关阵列和译码电路是整个设计的重点和难点,它们设计的好坏直接影响着dac电路特性的优劣。 - Consequently , an integrate switch mode power supply with high efficiency and good reliability can be realized by the controller with very few external parts . the fundamental principle of monolithic voltage - mode switching regulator is firstly introduced in this thesis , which is followed by a comparison between voltage - mode and current - mode converters where the pros and cons of both converters are discussed in detail ; next , the global system architecture is proposed upon the design requirements and sub - block circuits are also introduced that focuses on several essential sub - blocks such as amp , wave , pwm control , psc , osc and vref . finally , all sub - circuits and the whole chip circuit are simulated by hspice whose results indicate that the circuit function and performance have perfectly satisfied the design requirements
