Abstract:
The design and realization of a wideband variable gain amplifier for RF system is presented. The cascade of LNA and controllable attenuation makes the design have a 0-90dB gain adjustment range. Special care is devoted to the solution of typical problems encountered in the design of the amplifier, such as signal shielding and power supply decoupling. The amplifier uses passive amplitude-frequency equalization, 0.1-460MHz band variation is less than 1dB, the 3dB bandwidth is up to 520MHz. The noise characteristic is low, the total input referred noise is less than 15.5nV⁄√¯Hz.

Abstract:
Digital oscilloscope’s structure has analog signal acquisition circuit, which transforms signal’s amplitude to fit ADC dynamic range. This circuit is commonly called oscilloscope’s vertical or front-end amplifier. Difficulty in designing front-end amplifiers in GHz range largely affects higher frequency range oscilloscope’s price. This work is focused on designing a front-end amplifier using discrete and openly sold components. We propose a design for attenuator, buffer, variable gain circuits.

The radio frequency (RF) amplifiers are widely used in a variety of communication systems. However, the conventional analog RF resulted in reduced volage gain, magnitude, and phase responses. So, this work provides an overview of a research paper focused on the design and analysis of a single-stage variable gain amplifier (SSVGA) utilizing cascaded linear transconductance amplifier (Gm cell) and linear transimpedance amplifier (TIA) blocks with feedback via shunt resistors. The SSVGA architecture aims to maintain constant bandwidth while offering controllable voltage gain, making it versatile

Abstract:
Using a floating gate transistor, the sensor introduces a fully adaptable bio-potential sensor amp. Due to its recycling techniques, the theoretical limit of the new amplifier's sound performance factor (NEF) is less than 1.5. In addition, the concept of the original impermeable chip is intended for industrial use with a 0.35µm CMOS process. With the 2.5V source voltage, the average gain in the band is 40.7dB, and the rated input noise is 2.8µm. The amplifier bandwidth can be set to desired levels of 100Hz, 1 kHz, and 10 kHz, where its transmission capacity is rated effectively for audio features of 1.959, 2.0, and 2.2. Rejection of the usual method is measured more significantly than 70 dB If you set the Bandwidth to 10kHz, 60 dB variable frequency measured at 1kHz has a Total Harmonic Deviation (THD) of not greater than 0.1%. The projected amp too displays signs from various locations of the human being via scanning electro-encephalography, electro cardiography, electrooculography, and electro myography.

Abstract:
This chapter deals with digital method of calibration for analog integrated circuits as a means of extending its lifetime and reliability, which consequently affects the reliability the analog electronic system as a whole. The proposed method can compensate for drift in circuit’s electrical parameters, which occurs either in a long term due to aging and electrical stress or it is rather more acute, being caused by process, voltage and temperature variations. The chapter reveals the implementation of ultra-low voltage on-chip system of digitally calibrated variable-gain amplifier (VGA), fabricated in CMOS 130 nm technology. It operates reliably under supply voltage of 600mV with 10% variation, in temperature range from −20°C to 85°C. Simulations suggest that the system will preserve its parameters for at least 10 years of operation. Experimental verification over 10 packaged integrated circuit (IC) samples shows the input offset voltage of VGA is suppressed in range of 13μV to 167μV. With calibration the VGA closely meets its nominally designed essential specifications as voltage gain or bandwidth. Digital calibration is comprehensively compared to its widely used alternative, Chopper stabilization through its implementation for the same VGA.

Abstract:
In mmWave massive MIMO, the required number of radio frequency (RF) chains becomes impractical due to the expensive and power-hungry components such as variable gain power amplifiers, filters, mixers, and analog-to-digital/digital-to-analog converters (ADCs/DACs). A promising solution to this problem is reducing the number of radiofrequency (RF) chains by partitioning beamforming operations between the digital and RF domains, known as hybrid beamforming (HBF), while still achieving the near-optimal performance of the fully digital beamforming systems with much-reduced hardware complexity. This chapter reviews different HBF techniques for massive MIMO in 5G and radar systems. The basic HBF structures and their algorithm design is presented in the context of a point-to-point MIMO hybrid beamforming system. Then, some recently proposed HBF techniques for 5G and beyond networks are investigated, followed by a discussion about the benefit of HBF in MIMO radar systems.
