Single event transient (SET) pulse shapes caused by Au ions with an energy of 946 MeV were measured at the microprobe facility at GSI in Darmstadt. Using on-chip sense amplifiers, our novel approach allows observing SET pulse shapes at any interesting circuit node with negligible distortion. We were hence able to accurately trace the propagation of SET pulses through a 90 nm CMOS inverter chain.
The offer of information grows rapidly in mobile markets. The DVB-H standard as a part of DVB-T is an important carrier of information to a broad spectrum of consumers. New, cheap and robust receivers have to be developed, especially for handheld devices. We propose a high-speed operational amplifier for a low-pass filter in a direct conversion receiver. In order to integrate the receiver on a system...
An innovative design with simulation results of a low-voltage bulk driven mixer for direct conversion receiver is presented. The circuit is designed in a 65 nm digital CMOS process without analog extensions. It offers a conversion gain of 22 dB at a clock frequency of 1.5 GHz for GALILEO/GPS applications. The design is capable of operating at up to 7 GHz with only 3 dB gain decrease. The simulated...
This paper presents a low power CMOS down sampling micromixer in 65nm with an improved input stage. It is able to handle a superimposed DC current on the input port without degrading circuit performance. The mixer was fabricated in a triple-well process. A conversion gain of 17dB is achieved while only consuming 780muW from a 1.2V voltage supply up to a 3dB clock frequency of 600MHz. The gain decreases...
