    Abstract: Capacitive adjustment in an RCL resonant circuit is typically performed by adjusting a DC voltage being applied to one side of the capacitor. One side of the capacitor is usually connected to either the output node or the gate of a regenerative circuit in an RCL resonant circuit. The capacitance loading the resonant circuit becomes a function of the DC voltage and the AC sinusoidal signal generated by the resonant circuit. By capacitively coupling both nodes of the capacitor, a DC voltage can control the value of the capacitor over the full swing of the output waveform. In addition, instead of the RCL resonant circuit driving a single differential function loading the outputs, each output drives an independent single ended function; thereby providing two simultaneous operations being determined in place of the one differential function.

    Abstract: Very high frequency circuits suffer from parasitic resistances. At 60 GHz, conventional layout techniques can introduce loss into the circuit at critical locations. One critical interconnect between the output of a pre-driver and the gate of the final output stage causes 1 or 2 dB of loss due to the layout. By minimizing the number of via contacts, this conventional loss can be recovered using this new layout technique. In addition, a tap point of a via stack is used to modify the resonant characteristics of the interconnect. Finally, cross coupled devices in a resonant circuit are used to reduce the common mode noise at the expense of the common mode gain.

    Abstract: A phase lock loop (PLL) is an important component in wireless systems. CMOS technology offers voltage controlled oscillator designs operating at 60 GHz. One of the difficulties is dividing the high frequency clock down to a manageable clock frequency using conventional CMOS. Although injection locked dividers can divide down this clock frequency, these dividers have limitations. A divide by 2 is presented that uses several techniques; feed forward, clock amplification and series peaked inductors to overcome these limitations.

    Abstract: A Sallen-Key filter requires an operational amplifier with a large input impedance and a small output impedance. The operational amplifier requires an internal feedback path for stability that limits performance. This invention eliminates the need for internal feedback and increases the gain of a source follower which has characteristics matching the operational amplifier in the Sallen-Key filter. The source follower provides 6dB of AC voltage gain and is substituted for the operational amplifier. The Sallen-Key filter requires a differential configuration to generate all the required signals with their compliments and uses these signals in a feed forward path. Furthermore, a two n-channel stacked device maximizes the headroom voltage to several hundred millivolts for a 1.2V voltage supply in a 40nm CMOS technology. Thus, the required 880MHz bandwidth of the Sallen-Key filter can be easily met using the innovative source follower.

    Abstract: This invention eliminates the need for "capacitor coupling" or "transformer coupling," and the associated undesirable parasitic capacitance and inductance associated with these coupling techniques when designing high frequency (~60GHz) circuits. At this frequency, the distance between two adjacent stages needs to be minimized. A resonant circuit in series with the power or ground leads is used to isolate a biasing signal from a high frequency signal. The introduction of this resonant circuit allows a first stage to be "directly coupled" to a next stage using a metallic trace. The "direct coupling" technique passes both the high frequency signal and the biasing voltage to the next stage. The "direct coupling" approach overcomes the large die area usage when compared to either the "AC coupling" or "transformer coupling" approach since neither capacitors nor transformers are required to transfer the high frequency signals between stages.

    Abstract: A large gain is used to start up the oscillation of the crystal quickly. A control circuit disables a low resistance path based on the measured amplitude to reduce the power dissipation specification of the crystal. Another technique introduces a mixed-signal controlled power supply multi-path resistive array which tailors the maximum current to the crystal. A successive approximation register converts the amplitude into several partitions and enables/disables one of several power routing paths to the inverter of the oscillator. This allows a better match between the crystal selected by the customer and the on-chip drive circuitry to power up the oscillator without stressing the crystal. The "1/f" noise of the oscillator circuit is minimized by operating transistors in the triode region instead of the linear region.
