Flexible 200kHz-20MHz Oscillator - Customizable frequency, Low Power in TSMC 40nm

Overview

This macro-cell is a flexible general purpose oscillator core designed for TSMC 40nm CRN40LP CMOS technology. This IP can be customized upon customer request.
The customized CM4018hlf IP oscillates at a specific frequency selected between 200kHz and 20MHz, and consumes a proportional quiescent current (typ. 1.8uA to 13uA). An external 1.3uA bias current is required for proper operation, this can be implemented with Chipus CM1218hl voltage & current reference IP. A 4-bit digital bus allows frequency calibration against process variations with ±2.5% precision.
The core is easily retargeted to any other CMOS technology
due to its MOSFET-only oscillator architecture.
