Overview

The device consists of phase frequency detector (PFD), charge pump and lock detector (LD) PFD compares phases of a divided VCO signal and a divided reference oscillator signal. PFD feeds control signal to charge pump at signals mismatch. Charge pump output current forms VCO control voltage.
Lock detector forms output logical “1” at input signals phase coincidence.
The block is fabricated on SMIC CMOS 0.18 um technology.

Key features

  • SMIC CMOS 0.18 um
  • Charge pump current control (40 uA, 60 uA, 80 uA, 100 uA)
  • Wide range of charge pump output voltage (0.3 V…1.56 V)
  • PFD polarity selection
  • Lock time selection (64, 128, 216, 512 periods of reference frequency signal)
  • Without external components
  • Portable to other technologies (upon request)

Breaking new energy efficiency records with advanced power management platform

The free lunch offered for decades by Moore’s law is now over and scaling down to the next technology node no longer offers the required energy efficiency gains. Design teams must now pursue their gains by deploying increasingly complex power management techniques to meet the demands of the new IoT markets.

Guide to Choosing the Best LDO for Your Application

To know which LDO you need, you must first define the application of your LDO and then examine which parameters are most important when dealing with that application. With the multiple parameters that characterize a particular LDO, it is not easy to determine which LDO is best suited. To help you figure this out, we have put together this reference. This guide presents a list of all the key LDO parameters along with their definitions, the most common applications of LDOs, and which parameters are critical for each.
