Overview

A high-speed voltage clocked comparator with rail- to-rail outputs and no hysteresis. The typical propagation delay is 19ns while applying a differential input signal of 1mV over the offset voltage. The comparator operates with a supply voltage of 3.3V typical (VCC). The valid input voltage range is between 0.6V up to VCC. The comparator achieves an input offset voltage of ±1.04mV (3-sigma value). The circuit features an Enable signal turning on/off the comparator.

The comparator uses positive feedback (latch) to increase the comparison speed; thus, its operation consists of a reset phase and a regeneration (comparison) phase, which are controlled by the input clock (CLK). When CLK is ‘High’, the comparator is in the reset phase, and when it is ‘Low’, the comparator compares the voltages at INM and INP inputs and produces a 0 or VCC-level digital output voltage at the outputs DOUT and DOUTB. The CLK frequency is 2MHz. An output latch ensures that DOUT and DOUTB retain their previous values during reset phase.

The comparator features zero static current and low kickback noise. It requires a bias current of 89uA supplied from an external biasing circuit via the TAILBIAS input.

Achieving Groundbreaking Performance with a Digital PLL

This article compares analog, first-generation digital, and second-generation digital PLLs. It evaluates which type of PLL may be best in which situation. It further discloses a roadmap into other application areas, including general purpose / logic clocking, and regular low-jitter PLLs.

Improving Battery-Powered Device Operation Time Thanks To Power Efficient Sleep Mode

Allowing battery-powered devices to run, without battery recharge, for years rather than months, partakes in enhancing significantly end-user satisfaction and is a key point to enabling the emergence of IoT applications. Numerous applications, such as M2M, BLE, Zigbee…, have an activity rate (duty cycle) such that the power consumption in sleep mode dominates the overall current drawn by the SoC (System on Chip). For such applications, the design of the “Always-On power domain" (a.k.a AON power domain) is pivotal.

Generating High Speed CSI2 Video by an FPGA

In this article, we show how fast video streams conforming to MIPI CSI2 rev2.0 over MIPI DPHY rev1.2 can be generated, using VLSI Plus’ SVTPlus-CSI2-F IP core, with simple off-FPGA analog front-end. The high bit rates can be achieved with a relatively slow FPGA clock frequency, trading off FPGA resources for simple timing closure.
