This paper presents the design of an output-capacitor-free cascode low-dropout regulator (LDR) with low quiescent current and high power supply rejection (PSR) over a wide range of frequency. In the proposed LDR topology, power NMOS transistors are cascoded to isolate the core regulator from power supply ripples, thus providing high PSR even without any external filtering capacitors. By biasing the...
Power distribution network (PDN) of LSI has become one of important design parameters to reduce simultaneous switching noise for core circuits as well as I/O circuits. Power distribution network of LSI generally consists of meshed power and ground conductors and on-chip decoupling capacitors. For mobile communication and automotive applications, switching current of high-performance CMOS LSIs must...
In digital designs, it becomes more and more important to reduce the supply current variations (di/dt noise) they induce in the supply lines. This is due to the fact that steep variations in supply current give rise to EM (electro-magnetic) emission. Hence, integrated circuits with lower emission are greatly demanded, especially in the automotive market. This paper describes several efficient low...
An on-chip buck converter with 3D chip stacking is proposed and the operation is experimentally verified. The manufactured converter achieves a maximum power efficiency of 62% for an output current of 70mA with a switching frequency of 200MHz and a 2x2mm on-chip LC output filter in 0.35mum CMOS. The use of glass epoxy interposer to increase the maximum power efficiency up to 71.3%, and the power efficiency...
This paper describes experimental results on an orthogonal-core type linear motor with a new control system. This orthogonal-type linear motor has two power supply windings, and the velocity or direction of the moving parts can be easily controlled by regulating the voltage phase difference between the primary power supply winding and the secondary power supply winding. The excellent features of the...
