CURRENT CONTROLLED OSCILLATOR WITH REGULATED SYMMETRIC LOADS |
摘要 |
<p>An integrated circuit incorporating a bias circuit for a current-controlled oscillator (ICO) with improved power supply rejection ratio (PSRR) is described. The bias circuit for the ICO includes two error amplifiers. The first error amplifier regulates the bias voltage, VBN, referenced to a ground supply (GND). The second error amplifier regulates the bias voltage, VBP, referenced to a positive power supply (VDD). The VBP and VBN bias voltages have improved PSRR relative to conventional ICO bias circuits for noise injected into VDD and GND.</p> |
