A new type of relaxation oscillator is presented that combines excellent control linearity with low timing jitter. By using an alternative for the Schmitt trigger, the jitter caused by threshold level noise can be significantly reduced compared to a conventional relaxation oscillator, under equal conditions of control linearity. Circuits realized in a 0.8-m CMOS process show a typical measured distortion in the control characteristic of HD 2 = 67 dB and HD 3 = 90 dB (1 = 500 KHz), without using any feedback linearization techniques. The measured phase noise is 102 dBc/Hz at 10-kHz offset at osc = 1 5 MHz (65-ppm rms jitter) for a total supply current of 360 A.

“…A multivibrator oscillator VCO can be fully integrable. Much work on multivibrator VCOs has concentrated on their potential for excellent linearity [36][37][38][39][40], which is an important requirement when the PLL is being used for measurement or to demodulate a PM or FM signal. However, linearity is not as critical a requirement in clock recovery.…”

“…As in the harmonic case, the frequency usually depends on few critical elements, usually a capacitance value, a charging/discharging current, and a reference voltage. These values can usually be controlled well enough to give reasonably good frequency stability [36,37].…”

Methods are presented for the realization of MOS oscillators with multidecade tuning range and GHz top speed. The theory yields transistor-only circuits with robust, digital-like structures. These are relaxation networks capable of high frequency operation due to use of parasitic timing capacitors, simplified feedback networks, and submicron-channel transistors. NMOS and CMOS implementations are discussed.
