“…This system is analyzed in several papers [9], [13], [14] using current variables x and u of the form I 0 e V=V , where I 0 is a constant current, Vt = n(kT =q) is a real constant multiple of the thermal voltage, and V is a voltage representing the input or output signal. Unfortunately, this form for the variables cannot represent negative signals.…”

Abstract-An interfacing circuit for piezoresistive pressure sensors based on CMOS current conveyors is presented. The main advantages of the proposed interfacing circuit include the use of a single piezoresistor, the capability of offset compensation, and a versatile current-mode configuration, with current output and current or voltage input. Experimental tests confirm linear relation of output voltage versus piezoresistance variation.Index Terms-CMOS analog integrated circuit, current conveyor, current mode, interface circuit, pressure sensor.

“…As shown in schematic diagram Figure2and Figure3, the drain terminal of MOSFET needs a resistance to set the static base point of the circuit.The generation of PWM signal in this design selects LTC699x, which is a PWM driving chip with 20mA driving ability and adjustable frequency and duty cycle. In order to control the gate opening speed of MOSFET faster, a buffer ET74LVC14 is added between LTC699x and RC as the driver[4][5].…”

The transient characteristics of low dropout regulator (LDO) are very important to the final imaging effect of mobile phone camera. This design is a test module developed for the transient response test of LDO products. This module is cost-efficient and time-efficient and function-trimmed, and the test results are quantifiable and repeatable which satisfy the needs of transient response test of LDO products. This article describes the test principle of transient response and the hardware design and implementation of transient response module. The validity of such modules shown by the result of a real test of a 1A LDO. More importantly, it points out the details that should be paid attention to in the test process. It provides a reference for IC design engineers and application test engineers, and one can easily build modules according to this paper for practical testing.
