چکیده
Time interleaving is a technique that allows the use of multiple identical analog-to-digital converters1 (ADCs) to process regular sample data series at a faster rate than the operating sample rate of each individual data converter. In very simple terms, time interleaving (IL) consists of time multiplexing a parallel array of M identical ADCs, as shown in Figure 1, to achieve a higher net sample rate fs (with sampling period Ts = 1/fs) even though each ADC in the array is actually sampling (and converting) at the lower rate of fs/M. So, for example, by interleaving four 10-bit/100 MSPS ADCs one could in principle realize a 10-bit/400 MSPS ADC.

A zero-drift amplifier, as the name suggests, is an amplifier with offset voltage drift very close to zero. It uses autozero or chopping technology, or a combination of both, to continuously self-correct for dc errors over time and temperature. This enables the amplifier to achieve microvoltlevel offsets and extremely low offset drifts. Therefore, it is uniquely suited to be used in signal cond...

Used in a wide range of industrial, automotive, and commercial applications, electric motors are controlled by drives that vary the electrical input power to control the torque, speed, and position. High-performance motor drives can increase efficiency and deliver faster, more accurate control. Advanced motor-control systems combine control algorithms, industrial networks, and user interfaces, ...

Sensor misalignment is often a key consideration for high performance motion control systems that use MEMS inertial measurement units (IMUs) in their feedback loops. For the gyroscopes in the IMU, sensor misalignment describes the angular difference between each gyroscope’s axis of rotation and the system defined inertial reference frame, also known as the global frame. Managing the impact that...
