This paper presents a high linearity wide bandwidth low noise amplifier (LNA) MMIC with excellent noise figure. The amplifier topology is compromised of a single-stage cascode topology with inductive source degeneration of common-source device. This amplifier topology seems an attractive choice for applications requiring wide bandwidth, high gain, and high linearity. The design targets 700-900 MHz, 1700-2200 MHz, and 2500-2800 MHz frequency bands for GSM/WCDMA/LTE base station receiver applications. A single-stage amplifier is implemented in a high performance 0.25um InGaAs E/D-mode pHEMT technology and demonstrates a high gain and an excellent bandwidth along with a high-linearity. Additionally, an excellent noise performance is achieved demonstrating = +32.0 dBm while requiring only 45 mA from a +5V supply.

An X-Band Robust GaN Low-Noise Amplifier MMIC with sub 2 dB Noise Figure
Kazan, Oğuz; Koçer, Fatih; Aydın Çivi, Hatice Özlem (2018-11-19)
This paper presents a low-noise amplifier (LNA) operating between 8-11 GHz. Measurement results show that the LNA has a gain of more than 20 dB while achieving a noise figure of less than 2 dB. The three stage topology achieves high linearity, providing an OIP3 of 29 dBm at 0.6 W power dissipation. The robustness tests show that the circuit survives to at least 2.5 W (34 dBm) input power. With a size of just 2.8 x 1.3 mm(2) (3.6 mm(2)) the presented LNA is compact when compared to the state of the art. The ...
A Sigma Delta micro accelerometer with 6 mu g/root Hz resolution and 130 dB dynamic range
Sonmez, Ugur; Külah, Haluk; Akın, Tayfun (2014-11-01)
This paper reports the implementation of a low noise, high dynamic-range I I" pound readout for low cost capacitive Micro-Electro-Mechanical Systems (MEMS) accelerometers. The readout circuit sets the bandwidth of the I I" pound loop through an extra feedback path, and hence allows the closed loop system to operate with the low noise characteristics similar to a second-order I I" pound analog-to-digital converter. A thorough noise analysis of the proposed accelerometer shows that the mechanical noise is the...

Akın, Tayfun (2017-04-13)
This paper reports the development of a new digital microbolometer Readout Integrated Circuit (D-ROIC), called MT10212BD. It has a format of 1024 × 768 (XGA) and a pixel pitch of 12μm. MT10212BD is Mikro Tasarim’s second 12μm pitch microbolometer ROIC, which is developed specifically for surface micro machined microbolometer detector arrays with small pixel pitch using high-TCR pixel materials, such as VOx and a Si. MT10212BD has an alldigital system on-chip architecture, which generates programmable timing...
A 9.03 μW Low Noise Highly Tunable Analog Front-End for Fully Implantable Cochlear Prosthesis
Ozbek, Berkay; Külah, Haluk (2022-01-01)
This paper presents a low noise, low power and highly programmable analog front-end that can interface with an implantable acoustic sensor of a 12-channel fully implantable cochlear implant. Capable of processing outputs from a sensor higher than 20 μVrms as in the speech processors of conventional cochlear implants, the system mimics the filtering in the cochlea with 12 channels (85-6500 Hz) while consuming only 9.03 μW which is one of the lowest power consumption among the analog front-ends for the cochle...
