This paper presents a new background calibration technique employing an extra slow but accurate ADC for correcting the linear and nonlinear gain errors in pipelined ADCs. In comparison to the well-known skip---fill method, the proposed skip---swap al

This paper presents a new 0.5 V high-speed dynamic latch comparator with built-in foreground offset cancellation capability and rail-to-rail input range. Traditional latch comparators lose their speed performance in low voltage condition, especially

A new wideband, high linear passive sample and hold (S/H) structure is presented. Reducing the sampling switch voltage dependency on input signal is the key idea to linearize conventional S/H structure. The sampling switch is immunized from signal de

A new high-speed successive approximation analog-to-digital converter (ADC) architecture is presented. Two-bits extraction in each clock cycle is the key idea to double the conversion speed. Generating reference levels for three comparators with only

A push–pull silicon photonic Mach–Zehnder modulator (MZM) driver is presented which uses a switched capacitor approach to generate a ∼2 V peak-to-peak differential 4-level pulse amplitude modulation (PAM-4) signal. The driver chip includes a Gr

We demonstrate how to optimize the performance of PAM-4 transmitters based on lumped Silicon Photonic Mach-Zehnder Modulators (MZMs) for short-reach optical links. Firstly, we analyze the trade-off that occurs between extinction ratio and modulation
