Diode-triggered silicon-controlled rectifier (DT-SCR) devices protect sensitive circuit nodes, such as high-frequency analog circuits and thin-gate complementary metal-oxide semiconductor (CMOS) circuits with high-speed input [1]. Reducing the turn-on time and overshoot voltage enhances the use of a DTSCR device in high-speed applications. We analyze the two lateral bipolar devices found in CMOS based...
This This paper reports a new width tunable ultra wide-band (UWB) Gaussian monocycle pulse (GMP) generator for radar application. The circuit is a monolithic design in low cost CMOS technology and is area efficient. The GMP is generated with a square wave generator and then differentiated. The square wave generator is actually a glitch generator using a ring oscillator as the input. The differentiator...
This paper presents an equivalent current sensing technique for the applications o tests. This is accomplished by monitoring the operations of existing on-chip voltage regulators, which indirectly provides the IDDQ information. Equivalent IDDQ information is obtained by measuring an internal voltage signal of a regulator. Then, the measured data is shifted out using the IEEE 1149.1 standard. IDDQ...
