An L-2L through-line de-embedding method has been verified up to millimeter wave frequency. The parasitics of the pad can be modeled from the L-2L through-line. Measurement results of the transmission lines and transistors can be de-embedded by subtracting the parasitic matrix of the pad. Therefore, the de-embedding patterns, which is used for modeling active and passive devices, decrease great...

This paper presents a pre-amplifier latch based CMOS comparator design. This design is premeditated to be used as a comparator window. This design is attractive due to its low power dissipation and speed. Preamplifier implies a cascode structure which stabilizes the output voltage and latch with its regenerative feedback which makes comparison fast along with detection of small difference betwe...

A CMOS low noise amplifier with current folded technique has been proposed for ultra-low voltage, ultra-low power biomedical applications. The target frequency is 2.4 GHz and the proposed LNA is implemented in standard 65 and 90 nm CMOS technologies. By exploiting forward body biasing technique in current folded architecture, the LNA is biased in subthreshold region with supply voltage of 350 m...

A low-voltage low-power CMOS operational transconductance amplifier (OTA) with near rail-to-rail output swing is presented in this brief. The proposed circuit is based on the current-mirror OTA topology. In addition, several circuit techniques are adopted to enhance the voltage gain. Simulated from a 0.8-V supply voltage, the proposed OTA achieves a 62-dB dc gain and a gain–bandwidth product of...

This paper presented a method for the design of a high frequency CMOS operational amplifier. The OPAMP is designed using tsmc 0.18 micron CMOS technology which operates at 2.5V power supply. This is a two stage CMOS OPAMP which employs a miller capacitor. To design a two stage OPAMP is a multi-dimensional optimization problem where optimization of one or more parameters may easily result into d...

A design methodology for wideband CMOS low noise amplifier (LNA) with source degeneration is presented. By allowing an arbitrary source degeneration and employing a general input matching network, the minimum noise figure of the proposed wideband CMOS LNA can be made independent of the transistor width by properly choosing the source degeneration reactance. This result shows that the proposed t...

This paper presents the operation principle and silicon characterization of a power efficient ultra-low voltage area fully-differential, digital-based Operational Transconductance Amplifier (OTA), suitable for microscale biosensing applications (BioDIGOTA). Measured results in 180nm CMOS prototypes show that proposed BioDIGOTA is able to work with supply down 400 mV, consuming only 95 nW. Owing...
